1174889-93-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1174889-93-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,7,4,8,8 and 9 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1174889-93:
(9*1)+(8*1)+(7*7)+(6*4)+(5*8)+(4*8)+(3*9)+(2*9)+(1*3)=210
210 % 10 = 0
So 1174889-93-0 is a valid CAS Registry Number.

Reaction of thioacids with lsocyanates and lsothiocyanates: A convenient amide ligation process
Crich, David,Sasaki, Kaname
, p. 3514 - 3517 (2009)
Thiocarboxylates, prepared conveniently by cleavage of 9-fluorenylmethyl or trimethoxybenzyl thioesters, react at room temperature with isocyanates and isothiocyanates to give amide bonds in good to excellent yield. A carboxylate salt is also shown to rea
