Check Digit Verification of cas no

The CAS Registry Mumber 77067-12-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,0,6 and 7 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 77067-12:
(7*7)+(6*7)+(5*0)+(4*6)+(3*7)+(2*1)+(1*2)=140
140 % 10 = 0
So 77067-12-0 is a valid CAS Registry Number.

SYNTHESIS OF Δ3-DIHYDROTHIAPYRAN-1,1-DIOXIDES AND THEIR RAMBERG-BAECKLUND CONVERSION TO CYCLOPENTADIENES.

Burger, Jack J.,Chen, Tjoe B.R.A.,Waard, Eddy R. de,Huisman, Henk O.

, p. 1739 - 1742 (2007/10/02)

Treatment of Z-sulfone 1 with n-BuLi gives complete conversion to the cyclized anion 3.The anion 3 is protonated to 4.Reaction of 3 with hexachloroethane leads to a mixture of 4, 5 and 6.Ramberg-Baecklund rearrangement of 5 with one equivalent of n-BuLi a
