Check Digit Verification of cas no

The CAS Registry Mumber 1353719-73-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,5,3,7,1 and 9 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1353719-73:
(9*1)+(8*3)+(7*5)+(6*3)+(5*7)+(4*1)+(3*9)+(2*7)+(1*3)=169
169 % 10 = 9
So 1353719-73-9 is a valid CAS Registry Number.

Non-hydrogen bond catalyst-mediated diastereoselective conjugate additions of 5: H -oxazol-4-ones to o -hydroxyphenyl-substituted p -quinone methides

Fang, Fang,Huang, Anqi,Li, Pengfei,Li, Wenjun,Liu, Guokai,Wang, Ziyang

supporting information, p. 6807 - 6811 (2020/10/02)

An efficient DBU-catalyzed conjugate addition of 5H-oxazol-4-ones to o-hydroxyphenyl-substituted p-quinone methides has been developed, affording the valuable diarylmethanes in high yields with excellent diastereoselectivity. This strategy demonstrates a robust access to a wide range of diarylmethane derivatives possessing biologically significant o-hydroxyphenol and p-hydroxyphenol moieties under mild reaction conditions.
