81616-75-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 81616-75-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,6,1 and 6 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 81616-75:
(7*8)+(6*1)+(5*6)+(4*1)+(3*6)+(2*7)+(1*5)=133
133 % 10 = 3
So 81616-75-3 is a valid CAS Registry Number.

Rh-Catalyzed Coupling of Acrylic/Benzoic Acids with α-Diazocarbonyl Compounds: An Alternative Route for α-Pyrones and Isocoumarins

Hong, Chao,Liu, Zhanxiang,Yu, Shuling,Zhang, Yuhong

supporting information, p. 815 - 820 (2022/02/07)

A coupling of acrylic acids/benzoic acids with α-diazocarbonyl compounds has been realized by a combined catalytic system of rhodium catalyst and Zn(OAc)2 additive. The presence of Zn(OAc)2 obviously accelerates the C(sp2)

Macrolide Synthesis through Intramolecular Oxidative Cross-Coupling of Alkenes

Jiang, Bing,Zhao, Meng,Li, Shu-Sen,Xu, Yun-He,Loh, Teck-Peng

supporting information, p. 555 - 559 (2018/02/21)

A RhIII-catalyzed intramolecular oxidative cross-coupling between double bonds for the synthesis of macrolides is described. Under the optimized reaction conditions, macrocycles containing a diene moiety can be formed in reasonable yields and with excellent chemo- and stereoselectivity. This method provides an efficient approach to synthesize macrocyclic compounds containing a 1,3-conjugated diene structure.
