Check Digit Verification of cas no

The CAS Registry Mumber 77903-65-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,9,0 and 3 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 77903-65:
(7*7)+(6*7)+(5*9)+(4*0)+(3*3)+(2*6)+(1*5)=162
162 % 10 = 2
So 77903-65-2 is a valid CAS Registry Number.

Reactions of Aliphatic Imides with Oxalyl Chloride

Richter, Reinhard,Temme, George H.

, p. 3015 - 3017 (1981)

Simple aliphatic acid imides like diacetamide (1a), dipropionamide (1b), and diisobutyramide (6) react with oxalyl chloride with formation of O-acylated products of type 2a,b and 7, the structure of which was assigned on the basis of 1H-NMR and 13C-NMR data.Thermolysis of 2a,b results in HCl abstraction and ring closure, giving oxazolidinediones 5a,b.Heat treatment of 7 yields isobutyryl chloride and isobutyryl isocyanate.Glutarimide (10a) and adipimide (10b) yield fused heterocycles of type 12 directly when treated with oxalyl chloride.
