Check Digit Verification of cas no

The CAS Registry Mumber 1380540-05-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,8,0,5,4 and 0 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1380540-05:
(9*1)+(8*3)+(7*8)+(6*0)+(5*5)+(4*4)+(3*0)+(2*0)+(1*5)=135
135 % 10 = 5
So 1380540-05-5 is a valid CAS Registry Number.

Enantioselective diynylation of cyclic N-acyl ketimines: Access to chiral trifluoromethylated tertiary carbinamines

Zhang, Fa-Guang,Ma, Hai,Nie, Jing,Zheng, Yan,Gao, Qingzhi,Ma, Jun-An

supporting information; experimental part, p. 1422 - 1428 (2012/07/13)

A novel enantioselective diynylation of cyclic N-acyl trifluoromethylketimines with chloramphenicol-amine derivatives as chiral additives has been successfully developed. A series of diynylated tertiary trifluoromethylcarbinamines were obtained in high yields with good to excellent enantioselectivities (with up to 99% ee). Copyright
