Check Digit Verification of cas no

The CAS Registry Mumber 223716-25-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,3,7,1 and 6 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 223716-25:
(8*2)+(7*2)+(6*3)+(5*7)+(4*1)+(3*6)+(2*2)+(1*5)=114
114 % 10 = 4
So 223716-25-4 is a valid CAS Registry Number.

A new and efficient strategy for the preparation of 1,5,2- diazaphosphorines from primary β-enaminophosphonates

Palacios, Francisco,Ochoa de Retana, Ana M.,Oyarzabal, Julen

, p. 3091 - 3104 (1999)

A new and efficient synthesis of 1,5,2-diazaphosphorines is described. The key step is a base-induced heterocyclization of functionalized urea compounds. These compounds are formed by addition of primary β- enaminophosphonates to isocyanates.
