Check Digit Verification of cas no
The CAS Registry Mumber 389-44-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,8 and 9 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 389-44:
(5*3)+(4*8)+(3*9)+(2*4)+(1*4)=86
86 % 10 = 6
So 389-44-6 is a valid CAS Registry Number.

experimental part, p. 1350 - 1354 (2010/09/20)
1-Aryl-1H-benzotriazole derivatives were synthesized via intramolecular cyclization of easily obtained triazenes, using CuI as the catalyst, DMSO as the solvent, t-BuONa as the base, and 1,10-phenanthroline as the ligand, in up to 97% yield. The synthesis is regiospecific and functional grouptolerant.
