Check Digit Verification of cas no

The CAS Registry Mumber 65138-50-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,1,3 and 8 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 65138-50:
(7*6)+(6*5)+(5*1)+(4*3)+(3*8)+(2*5)+(1*0)=123
123 % 10 = 3
So 65138-50-3 is a valid CAS Registry Number.

Four- and Five-membered Phosphorus Heterocycles, 39. Structural Changes on the Cycloaddition of Ketones to Azaphospholes

Sheldrick, William S.,Schomburg, Dietmar,Schmidpeter, Alfred,Criegern, Thomas von

, p. 55 - 69 (2007/10/02)

The reaction of 5H-1,2λ5-azaphospholes 1 with ketones yields stable cycloadducts 3 possessing a bicycloheptane skeleton with pentacoordinate phosphorus in a bridge-head.It shows once again the enhanced addition capability of five
