Check Digit Verification of cas no

The CAS Registry Mumber 203317-34-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,3,3,1 and 7 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 203317-34:
(8*2)+(7*0)+(6*3)+(5*3)+(4*1)+(3*7)+(2*3)+(1*4)=84
84 % 10 = 4
So 203317-34-4 is a valid CAS Registry Number.

A stereoselective synthesis of trans-1,2-disubstituted alkenes based on the condensation of aldehydes with metallated 1-phenyl-1H-tetrazol-5-yl sulfones

Blakemore, Paul R.,Cole, William J.,Kocieński, Philip J.,Morley, Andrew

, p. 26 - 28 (2007/10/03)

The reaction of metallated 1-phenyl-1H-tetrazol-5-yl sulfones and aldehydes gives good yields and stereoselectivity of trans-1,2-disubstituted alkenes when potassium or sodium hexamethyldisilazide is used as base and 1,2-dimethoxyethane is used as solvent.
