Check Digit Verification of cas no

The CAS Registry Mumber 1027992-72-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,7,9,9 and 2 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1027992-72:
(9*1)+(8*0)+(7*2)+(6*7)+(5*9)+(4*9)+(3*2)+(2*7)+(1*2)=168
168 % 10 = 8
So 1027992-72-8 is a valid CAS Registry Number.

Unexpected Z-stereoselectivity in the Ramberg-Baecklund reaction of diarylsulfones leading to cis-stilbenes: The effect of aryl substituants and application in the synthesis of the integrastatin nucleus

Foot, Jonathan S.,Giblin, Gerard M.P.,Whitwood,Taylor

, p. 756 - 763 (2007/10/03)

With certain substituent patterns, benzyl benzyl sulfone systems have been found to give unexpectedly high Z-stereoselectivity (up to E : Z = 1 : 16) in the Meyers variant of the Ramberg-Baecklund reaction. A range of sulfones, bearing various aryl substi
