Calculate Digit Verification of CAS Registry Number 126863-86:
(8*1)+(7*2)+(6*6)+(5*8)+(4*6)+(3*3)+(2*8)+(1*6)=153
153 % 10 = 3
So 126863-86-3 is a valid CAS Registry Number.

CONTROL OF REGIOCHEMISTRY, STEREOCHEMISTRY AND STOICHIOMETRY IN ADDITIONS TO ALKADIYNES. SYNTHETIC VALUE OF A SULFONE FUNCTION.

Thyagarajan, Budalur S.,Chandler, Richard Allen

, p. 53 - 61 (2007/10/02)

The strategic placement of a sulfone function alpha to a conjugated alkadiyne is shown to enforce total control of regiochemistry, stereochemistry and stoichiometry in additions of nucleophiles across the triple bonds.
