Check Digit Verification of cas no

The CAS Registry Mumber 131023-16-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,0,2 and 3 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 131023-16:
(8*1)+(7*3)+(6*1)+(5*0)+(4*2)+(3*3)+(2*1)+(1*6)=60
60 % 10 = 0
So 131023-16-0 is a valid CAS Registry Number.

On Triazoles. XXI. Synthesis of 1,2,4-Triazolyldithiocarbonates

Pongo, Laszlo,Reiter, Jozsef,Barkoczy, Jozsef,Sohar, Pal,Pallagi, Istvan

, p. 1249 - 1257 (2007/10/02)

The reaction of 5-amino-1,2,4-triazoles 1 with carbon disulfide and alkylating agents in basic condition to yield alkyl, aralkyl and aryl (5-amino-3-Q-1,2,4-triazol-1-yl)dithiocarbonates 2 and alkyl (3-Q-1,2,4-triazol-5-ylamino)dithiocarbonates 3 was studied.The isomeric and tautomeric structure of derivatives obtained was proved with the help of their uv, pmr and cmr spectra using model compounds prepared for this purpose.The results obtained enabled us to correct some confusion in the literature.
