Check Digit Verification of cas no

The CAS Registry Mumber 1309979-52-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,9,9,7 and 9 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1309979-52:
(9*1)+(8*3)+(7*0)+(6*9)+(5*9)+(4*7)+(3*9)+(2*5)+(1*2)=199
199 % 10 = 9
So 1309979-52-9 is a valid CAS Registry Number.

Enantioselective organocatalytic Michael-hemiketalization catalyzed by a trans-bifunctional indane thiourea catalyst

Gao, Yaojun,Ren, Qiao,Ang, Swee-Meng,Wang, Jian

, p. 3691 - 3697 (2011)

An efficient, convenient and enantioselective Michael-hemiketalization reaction has been developed for the synthesis of naphthoquinones. In this work, a novel trans-bifunctional indane thiourea catalyst has been reported to promote this process to afford
