Check Digit Verification of cas no

The CAS Registry Mumber 1398508-07-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,9,8,5,0 and 8 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1398508-07:
(9*1)+(8*3)+(7*9)+(6*8)+(5*5)+(4*0)+(3*8)+(2*0)+(1*7)=200
200 % 10 = 0
So 1398508-07-0 is a valid CAS Registry Number.

Stereoselective conjugate addition of ketones to alkylidene malonates using thiourea-sulfonamide organocatalyst

Kawada, Masahiro,Nakashima, Kosuke,Hirashima, Shin-ichi,Sakagami, Toru,Koseki, Yuji,Miura, Tsuyoshi

, p. 1215 - 1224 (2018/09/25)

In this study, stereoselective conjugate addition of ketones to alkylidene malonates using organocatalyst has been developed. The reaction in the presence of 20?mol% of a novel thiourea-sulfonamide organocatalyst afforded conjugate adducts in moderate to

Highly enantioselective michael addition of ketone to alkylidene malonates catalyzed by binaphthyl sulfonimides in water

Jia, Shengjian,Luo, Chunhua,Du, Daming

, p. 2676 - 2680 (2013/01/15)

Binaphthyl sulfonimides have been developed to catalyze the asymmetric Michael addition of ketone to alkylidene malonates, affording the corresponding Michael products in good to high yields (up to 98%) with good to excellent diastereoselectivity (up to 9

Highly enantioselective conjugate addition of ketones to alkylidene malonates catalyzed by a pyrrolidinyl-camphor-derived organocatalyst

Magar, Dhananjay R.,Chang, Chihliang,Ting, Ying-Fang,Chen, Kwunmin

supporting information; experimental part, p. 2062 - 2066 (2010/06/15)

Pyrrolidinyl-camphor derivatives have been proven to be efficient organocatalysts for enantioselective conjugate addition of ketones to alkylidene malonates, affording high chemical yields (up to 95 %) of the corresponding products with high to excellent levels of diastereoselectivity (up to >99:1 dr) and enantioselectivity (up to 96%ee) under solvent-free reaction conditions at ambient temperature.
