Check Digit Verification of cas no

The CAS Registry Mumber 74445-12-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,4,4 and 5 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 74445-12:
(7*7)+(6*4)+(5*4)+(4*4)+(3*5)+(2*1)+(1*2)=128
128 % 10 = 8
So 74445-12-8 is a valid CAS Registry Number.

Preparation, Reactions and Structures of Spirobicyclic Phosphoranes

Roesky, Herbert W.,Ambrosius, Klaus,Banek, Manfred,Sheldrick, William S.

, p. 1847 - 1854 (2007/10/02)

By the reaction of trimethylsilyl-substituted ureas with dichlorophenylphosphane we obtained the spirobicyclic phosphoranes 1b and 1c with a λ3P-λ5P-bond.With chlorine or PCl5 1a - c react under elimination of dichlorophenylphosphane
