Check Digit Verification of cas no

The CAS Registry Mumber 81129-82-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,1,2 and 9 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 81129-82:
(7*8)+(6*1)+(5*1)+(4*2)+(3*9)+(2*8)+(1*2)=120
120 % 10 = 0
So 81129-82-0 is a valid CAS Registry Number.

An Efficient Synthesis of the Enantiomeric 17-Phosphasteroid System

Bodalski, Ryszard,Koszuk, Jacek,Krawczyk, Henryk,Pietrusiewicz, K. Michal

, p. 2219 - 2220 (2007/10/02)

Enantiomeric trans-benzylphenylphosphine oxide (6) undergoes regio- and stereoselective cycloaddition to 1-vinylnaphthalene (5), providing two diastereomeric adducts 7a and 7b, which are further transformed into optically pure 17-phosphasteroid systems by intramolecular Dieckmann-type condensation.
