Check Digit Verification of cas no
The CAS Registry Mumber 127627-22-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,6,2 and 7 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 127627-22:
(8*1)+(7*2)+(6*7)+(5*6)+(4*2)+(3*7)+(2*2)+(1*2)=129
129 % 10 = 9
So 127627-22-9 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
