Check Digit Verification of cas no

The CAS Registry Mumber 97985-67-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,9,8 and 5 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 97985-67:
(7*9)+(6*7)+(5*9)+(4*8)+(3*5)+(2*6)+(1*7)=216
216 % 10 = 6
So 97985-67-6 is a valid CAS Registry Number.

Asymmetric epoxidation of α,β-unsaturated aldehydes catalyzed by a spiro-pyrrolidine-derived organocatalyst

Xu, Ming-Hui,Tu, Yong-Qiang,Tian, Jin-Miao,Zhang, Fu-Min,Wang, Shao-Hua,Zhang, Shi-Heng,Zhang, Xiao-Ming

supporting information, p. 294 - 300 (2017/03/01)

The asymmetric epoxidation of α,β-unsaturated aldehydes, catalyzed by a spiro-pyrrolidine (SPD)-derived organocatalyst, has been accomplished with good diastereoselectivities (up to dr >20:1) and with high to excellent enantioselectivities (up to 99% ee).

EPOXIDATION OF trans-3-ARYLPROPENALS BY tert-BUTYL HYDROPEROXIDE

Revinskii, I. F.,Tishchenko, I. G.,Burd', V. N.,Bubel', O. N.

, p. 637 - 641 (2007/10/02)

The products and the kinetics of the epoxidation of trans-3-arylpropenals with tert-butyl hydrogen peroxide in an alkaline medium were studied.The epoxidation rate increases with increase in the electron-withdrawing characteristics of the substituents in the aryl fragment of cinnamaldehydes.
