Check Digit Verification of cas no

The CAS Registry Mumber 1616778-04-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,1,6,7,7 and 8 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1616778-04:
(9*1)+(8*6)+(7*1)+(6*6)+(5*7)+(4*7)+(3*8)+(2*0)+(1*4)=191
191 % 10 = 1
So 1616778-04-1 is a valid CAS Registry Number.

Catalytic hetero-ene reactions of 5-methyleneoxazolines: Highly enantioselective synthesis of 2,5-disubstituted oxazole derivatives

Luo, Weiwei,Zhao, Jiannan,Yin, Chengkai,Liu, Xiaohua,Lin, Lili,Feng, Xiaoming

supporting information, p. 7524 - 7526 (2014/07/07)

An efficient catalytic asymmetric hetero-ene reaction of 5-methyleneoxazolines with 1,2-dicarbonyl compounds (including α-ketoesters and glyoxal derivatives) was realized using Ni(ii)-N,N′-dioxide complexes as the catalysts. It provides a rapid, high yielding (up to 99%) route for the preparation of 2,5-disubstituted oxazole derivatives in a highly enantioenriched form (up to >99% ee) under mild conditions. the Partner Organisations 2014.
