Check Digit Verification of cas no
The CAS Registry Mumber 31350-27-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,3,5 and 0 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 31350-27:
(7*3)+(6*1)+(5*3)+(4*5)+(3*0)+(2*2)+(1*7)=73
73 % 10 = 3
So 31350-27-3 is a valid CAS Registry Number.

HMDS-promoted in situ amidation reactions of carboxylic acids and amines
Chou, Wen-Chih,Chou, Ming-Chen,Lu, Yann-Yu,Chen, Shyh-Fong
, p. 3419 - 3422 (1999)
A number of N-acylalkylenediamines were synthesized in high yields by in situ monoamidation of carboxylic acids with diamines. The amidation reactions were carried out simply by heating the substrates at 110 °C for 5-24 h in the presence of HMDS.
