Check Digit Verification of cas no

The CAS Registry Mumber 81027-61-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,0,2 and 7 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 81027-61:
(7*8)+(6*1)+(5*0)+(4*2)+(3*7)+(2*6)+(1*1)=104
104 % 10 = 4
So 81027-61-4 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.
