Check Digit Verification of cas no

The CAS Registry Mumber 1231728-70-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,1,7,2 and 8 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1231728-70:
(9*1)+(8*2)+(7*3)+(6*1)+(5*7)+(4*2)+(3*8)+(2*7)+(1*0)=133
133 % 10 = 3
So 1231728-70-3 is a valid CAS Registry Number.

Nucleophilic perfluoroalkylation of imines and carbonyls: Perfluoroalkyl sulfones as efficient perfluoroalkyl-transfer motifs

Prakash, G. K. Surya,Wang, Ying,Mogi, Ryo,Hu, Jinbo,Mathew, Thomas,Olah, George A.

supporting information; experimental part, p. 2932 - 2935 (2010/09/09)

Alkoxide-induced nucleophilic pentafluoroethylation and trifluoromethylation of aldehydes, ketones, and imines using pentafluoroethyl phenyl sulfone (PhSO2CF2CF3, 1) and trifluoromethyl phenyl sulfone (PhSO2CF3, 2), respectively, have been successfully achieved. High diastereoselectivity was observed during the perfluoroalkylation of homochiral sulfinimines to give the corresponding perfluoroalkyl sulfinamides.
