Check Digit Verification of cas no

The CAS Registry Mumber 122179-82-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,2,1,7 and 9 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 122179-82:
(8*1)+(7*2)+(6*2)+(5*1)+(4*7)+(3*9)+(2*8)+(1*2)=112
112 % 10 = 2
So 122179-82-2 is a valid CAS Registry Number.

A Simple and Economic Synthesis of Monoacylated Alkanediamines by Thermal Transamidation

Zaragoza-Doerwald, Florencio,Kiedrowski, Guenter von

, p. 917 - 918 (2007/10/02)

N-(ω-Aminoalkyl)amides 2 are easily synthesized by heating mixtures of excess α,ω-alkanediamines 1 and primary amides to temperatures between 150 deg C and 200 deg C, at which thermal transamidation occurs.Under the reaction conditions ammonia is released, and 2 is in equilibrium with the alkanediamine 1 and the α,ω-bis(acylamino)alkane 3.Thus, thermal transamidation is a practicable way to overcome the problem of diacylation which appears as an often recognized problem even in the latest literature.
