Check Digit Verification of cas no

The CAS Registry Mumber 22158-84-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,1,5 and 8 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 22158-84:
(7*2)+(6*2)+(5*1)+(4*5)+(3*8)+(2*8)+(1*4)=95
95 % 10 = 5
So 22158-84-5 is a valid CAS Registry Number.

Efficient synthesis of α-tertiary α-silylamines from aryl sulfonylimidates via one-pot, sequential C-Si/C-C bond formations

Han, Xiao-Jun,Yao, Ming,Lu, Chong-Dao

supporting information; experimental part, p. 2906 - 2909 (2012/07/14)

An efficient and flexible route for the synthesis of α-tertiary (α,α-dibranched) α-silylamines via sequential reactions of sulfonylimidates using readily available phenyldimethylsilyllithium and Grignard reagents is described. The procedure allows successive formation of C-Si/C-C bonds in a single flask.
