252668-08-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 252668-08-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,2,6,6 and 8 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 252668-08:
(8*2)+(7*5)+(6*2)+(5*6)+(4*6)+(3*8)+(2*0)+(1*8)=149
149 % 10 = 9
So 252668-08-9 is a valid CAS Registry Number.

Novel synthesis and cyclization reactions of 3-amino-2-mercaptopyrrole derivatives
El-Sharief,Ammar,Mohamed,El-Gaby
, p. 117 - 130 (2007/10/03)
Interaction of cyanothioformamides with chalcones gave 3-amino-2-mercaptopyrroles, which have the tautomeric structures (3-aminopyrroline-2-thiones and 3-iminopyrrolidine-2-thiones). The latter was reacted with chloroacetic acid, ethyl chloroacetate, chlo
