149681-70-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 149681-70-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,9,6,8 and 1 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 149681-70:
(8*1)+(7*4)+(6*9)+(5*6)+(4*8)+(3*1)+(2*7)+(1*0)=169
169 % 10 = 9
So 149681-70-9 is a valid CAS Registry Number.

A new synthesis of thioamides and dithiocarbamates from organolithium derivatives
Gronowitz,Hornfeldt,Temciuc
, p. 483 - 484 (1993)
The reaction of organolithium derivatives with thiuram monosulfides gives a convenient method for the synthesis of both aromatic and aliphatic thioamides in good yields. In our hands, the reaction of organolithium derivatives with tetramethylthiuram disul
