Check Digit Verification of cas no

The CAS Registry Mumber 1286740-01-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,6,7,4 and 0 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1286740-01:
(9*1)+(8*2)+(7*8)+(6*6)+(5*7)+(4*4)+(3*0)+(2*0)+(1*1)=169
169 % 10 = 9
So 1286740-01-9 is a valid CAS Registry Number.

From difluoromethyl 2-pyridyl sulfone to difluorinated sulfonates: A protocol for nucleophilic difluoro(sulfonato)methylation

Prakash, G. K. Surya,Ni, Chuanfa,Wang, Fang,Hu, Jinbo,Olah, George A.

, p. 2559 - 2563 (2011/04/26)

An efficient method for the synthesis of alkyl α,α- difluorosulfonates has been developed. The selection of the 2-pyridyl group as the aryl substitute on the sulfone is critically important for the success of this transformation (see scheme). The synthetic application of fluorinated sulfones is extended and a unique solution is provided for a long-standing challenge in nucleophilic difluoro(sulfonato)methylation reactions. Copyright
