127719-83-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 127719-83-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,7,1 and 9 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 127719-83:
(8*1)+(7*2)+(6*7)+(5*7)+(4*1)+(3*9)+(2*8)+(1*3)=149
149 % 10 = 9
So 127719-83-9 is a valid CAS Registry Number.

Thiohydrazides and 1,3,4-Thiadiazoles by Hydrazinolysis of Dithiocarboxylic Esters
Thiel, W.,Mayer, R.
, p. 649 - 658 (2007/10/02)
The reaction of 1,1-dithiooxalicesters 1 and heteroaryldithiocarboxylic esters 2 with excess hydrazine yields stable thiohydrazides 3 and 4, respectively.If the hydrazinolysis is carried out with only 0.5 equivalent hydrazine 1,3,4-thiadiazoles 6 and 7, e
