Check Digit Verification of cas no

The CAS Registry Mumber 13172-83-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,1,7 and 2 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 13172-83:
(7*1)+(6*3)+(5*1)+(4*7)+(3*2)+(2*8)+(1*3)=83
83 % 10 = 3
So 13172-83-3 is a valid CAS Registry Number.

, p. 2491 - 2496 (2007/10/03)

A new route for the synthesis of some mixed organic phosphorus compounds from 1,3-dioxolan-2-one is reported. By heating a mixture of phosphorus-chlorine derivatives and 1,3-dioxolan-2-one in the presence of a catalyst, mixed phosphorus derivatives having 2-chloroethyl ester groups could be obtained. A wide range of phosphorus derivatives can be obtained using this method.
