Check Digit Verification of cas no

The CAS Registry Mumber 1003444-36-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,0,3,4,4 and 4 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1003444-36:
(9*1)+(8*0)+(7*0)+(6*3)+(5*4)+(4*4)+(3*4)+(2*3)+(1*6)=87
87 % 10 = 7
So 1003444-36-7 is a valid CAS Registry Number.

Borate esters as convenient reagents for direct amidation of carboxylic acids and transamidation of primary amides

Starkov, Pavel,Sheppard, Tom D.

, p. 1320 - 1323 (2011)

Simple borates serve as effective promoters for amide bond formation with a variety of carboxylic acids and amines. With trimethyl or tris(2,2,2- trifluoroethyl) borate, amides are obtained in good to excellent yield and high purity after a simple work-up procedure. Tris(2,2,2-trifluoroethyl) borate can also be used for the straightforward conversion of primary amides to secondary amides via transamidation. The Royal Society of Chemistry 2011.
