Check Digit Verification of cas no

The CAS Registry Mumber 1390849-60-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,9,0,8,4 and 9 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1390849-60:
(9*1)+(8*3)+(7*9)+(6*0)+(5*8)+(4*4)+(3*9)+(2*6)+(1*0)=191
191 % 10 = 1
So 1390849-60-1 is a valid CAS Registry Number.

Diastereoselective Synthesis of Tetracyclic Tetrahydroquinoline Derivative Enabled by Multicomponent Reaction of Isocyanide, Allenoate, and 2-Aminochalcone

Wang, Zhishuang,Fei, Youwen,Tang, Chongrong,Cui, Lei,Shen, Jie,Yin, Kun,Lu, Shanya,Li, Jian

supporting information, p. 4094 - 4098 (2021/05/26)

We report here a multicomponent protocol to assemble several polycyclic dihydropyran-fused tetrahydroquinoline structures with excellent diastereoselectivity. This procedure employs simple feedstocks to accomplish a series of diverse structures, which is

Visible-Light Induction/Br?nsted Acid Catalysis in Relay for the Enantioselective Synthesis of Tetrahydroquinolines

Xiong, Wenhui,Li, Shan,Fu, Bo,Wang, Jinping,Wang, Qiu-An,Yang, Wen

supporting information, p. 4173 - 4176 (2019/06/07)

An efficient method merging Br?nsted acid catalysis with visible-light induction for the highly enantioselective synthesis of tetrahydroquinolines has been developed. This mild process directly transforms 2-aminoenones into 2-substituted tetrahydroquinolines with excellent enantioselectivities through a relay visible-light-induced cyclization/chiral phosphoric acid-catalyzed transfer hydrogenation reaction.

Pd-catalyzed cross-coupling of aryl carboxylic acids with propiophenones through a combination of decarboxylation and dehydrogenation

Zhou, Jun,Wu, Ge,Zhang, Min,Jie, Xiaoming,Su, Weiping

supporting information; experimental part, p. 8032 - 8036 (2012/08/13)

A palladium-catalyzed cross-coupling reaction of aryl carboxylic acids with saturated propiophenones through a combination of decarboxylation and dehydrogenation to form Heck-type products was reported. In a glove box, a 25 mL tube equipped with a stir bar was charged with Pd(OAc)2, PCy3, propiophenone, 2-nitrobenzoic acid, Ag2CO3 and nBu4NOAc HOAc. Then, the mixture was heated under nitrogen at 90°C in DMF for 24 h. After cooling down, the crude reaction mixture was analyzed by GC with n-dodecane as an internal standard to obtain 3a in 75% GC yield. Relatively weak bases, such as carboxylate salts, facilitated this reaction and the effect of the bases was a function of their solubility, while strong bases, such as K3PO4 and K2CO3 shut down the reaction completely. The simultaneous use of carboxylate salts and equimolar carboxylic acids significantly improved the yield of 3a, although the use of acetic acid alone was ineffective for the reaction.
