Check Digit Verification of cas no

The CAS Registry Mumber 42729-82-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,7,2 and 9 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 42729-82:
(7*4)+(6*2)+(5*7)+(4*2)+(3*9)+(2*8)+(1*2)=128
128 % 10 = 8
So 42729-82-8 is a valid CAS Registry Number.

Amides in one pot from Carboxylic Acids and Amines via Sulfinylamides

Bai, Jianfei,Zambron, Bartosz K.,Vogel, Pierre

supporting information, p. 604 - 607 (2014/04/03)

An efficient method has been developed for the direct amidification of carboxylic acids via sulfinylamides preformed in situ by the reaction of pure amines with prop-2- ene-1-sulfinyl chloride. The method can be applied to aliphatic acids, including pivalic acid, aromatic acids, and primary and secondary amines. It is compatible with acids bearing unprotected alcohol, phenol, and ketone moieties and applicable to the synthesis of peptides. It does not induce their a-epimerization.
