174875-93-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 174875-93-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,4,8,7 and 5 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 174875-93:
(8*1)+(7*7)+(6*4)+(5*8)+(4*7)+(3*5)+(2*9)+(1*3)=185
185 % 10 = 5
So 174875-93-5 is a valid CAS Registry Number.

Synthesis of heterocyclic ketene aminals with a β-hydroxyethyl group on the nitrogen atom
Wang, Li-Ben,Huang, Zhi-Tang
, p. 459 - 473 (2007/10/03)
The heterocyclic ketene aminals 4 with a β-hydroxyethyl group on the nitrogen atom are synthesized by the reaction of the corresponding ketene mercaptals 3 with 2-(2-aminoethylamino)ethanol. In the case of 3 with one aroyl substituent, besides the ketene
