Check Digit Verification of cas no

The CAS Registry Mumber 1259940-18-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,9,9,4 and 0 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1259940-18:
(9*1)+(8*2)+(7*5)+(6*9)+(5*9)+(4*4)+(3*0)+(2*1)+(1*8)=185
185 % 10 = 5
So 1259940-18-5 is a valid CAS Registry Number.

Stereoselective synthesis of phenyl-1,2,3-triazoles containing (E)-vinyl halide group via a one-pot, three-component reaction

Zhang, Wensheng,Su, Changhui,Kuang, Chunxiang,Yang, Qing

, p. 1267 - 1275 (2011)

Phenyl-1,2,3-triazoles containing (E)-vinyl halide were readily synthesized via a one-pot, three-component reaction of 3-(4- or 2-azidophenyl)acrylic acid, NXS(X=Cl, Br and I) and 1-alkynes in MeCN-H2O (9:1v/v) catalyzed by LiOAc/CuI-sodium ascorbate syst
