Check Digit Verification of cas no

The CAS Registry Mumber 134832-82-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,8,3 and 2 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 134832-82:
(8*1)+(7*3)+(6*4)+(5*8)+(4*3)+(3*2)+(2*8)+(1*2)=129
129 % 10 = 9
So 134832-82-9 is a valid CAS Registry Number.

Thiocarbazinic acids: Interaction of carbonoxysulphide with thiosemicarbazides - Synthesis of &β-(thiocarbamyl)thiocarbazinates and 1,3,4-oxadiazole and 1,2,4-triazole derivatives

Chande, Madhukar S.,Karnik, Anil V,Inamdar, Arvind N,Damle, Shruti D

, p. 430 - 432 (2007/10/02)

Interaction of carbon oxysulphide with 4-alkyl/arylthiosemicarbazides (I) in ethanol in the presence of sodium hydroxide forms sodium β-(N-alkyl/arylthiocarbamyl)thiocarbazinates (II).Benzylation of the latter (II) affords 5-alkyl/arylamino-2-benzylmercapto-1,3,4-oxadiazoles (IV), which can also be obtained by a one-pot synthesis involving the reaction of I with carbon oxysulphide in DMF in the presence of triethylamine and benzyl chloride.The syntheses of benzyl β-(N-alkyl/arylthiocarbamyl)thiocarbazinates (III) and 4-aryl-3-mercapto-1,2,4-triazolin-5-ones (VII) are also reported.Some of the compounds exhibit antibacterial activity.
