Check Digit Verification of cas no
The CAS Registry Mumber 1519-21-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,1 and 9 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1519-21:
(6*1)+(5*5)+(4*1)+(3*9)+(2*2)+(1*1)=67
67 % 10 = 7
So 1519-21-7 is a valid CAS Registry Number.

Homobenzotetramisole-catalyzed kinetic resolution of α-Aryl-, α-Aryloxy-, and α-Arylthioalkanoic acids
Yang, Xing,Birman, Vladimir B.
supporting information; experimental part, p. 2301 - 2304 (2010/01/19)
Effective kinetic resolutions of α-aryl-, αaryloxy-, and α-arylthioalkanoic acids have been achieved via in situ generation of their symmetrical anhydrides and enantioselective alcoholysis in the presence of homobenzotetramisole (HBTM) 3.
Preparation of 5-substituted 2-methyl-1,3,4-oxadiazoles from 5- substituted tetrazoles and acetic anhydride
Jursic,Zdravkovski
, p. 1575 - 1582 (2007/10/02)
Readily available tetrazoles can be transformed into the corresponding 2- methyl-1,3,4-oxazodiazoles by heating their acetic anhydride solution. The procedure is simple, short, gives high yields, and is applicable to large scale syntheses.
