Check Digit Verification of cas no

The CAS Registry Mumber 1117816-15-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,1,7,8,1 and 6 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1117816-15:
(9*1)+(8*1)+(7*1)+(6*7)+(5*8)+(4*1)+(3*6)+(2*1)+(1*5)=135
135 % 10 = 5
So 1117816-15-5 is a valid CAS Registry Number.

Reactions of hydrazonoyl halides 561: Synthesis and reactions of 1-bromo-2-(5-chloro-benzofuranyl)ethanedione-1-phenylhydrazone

Abdelhamid, Abdou O.,El-Ghandour, Ahmed H.,El-Reedy, Ahmed A. M.

experimental part, p. 1272 - 1284 (2009/04/10)

2,3-Dihydro-1,3,4-thiadiazoles and triazolino[4,3-a]pyrimidines containing benzofuran moiety were prepared from reaction of 1-bromo-2-(5- chlorobenzofuranyl) ethanedione-1-phenylhydrazone with each of potassium thiocyanate, alkyl carbodithioates and pyrmidine-2-thiones. All newly synthesized were confirmed by elemental analysis, spectral data, and alternative route synthesis whenever possible. Copyright Taylor & Francis Group, LLC.
