Check Digit Verification of cas no
The CAS Registry Mumber 1353752-33-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,5,3,7,5 and 2 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1353752-33:
(9*1)+(8*3)+(7*5)+(6*3)+(5*7)+(4*5)+(3*2)+(2*3)+(1*3)=156

, p. 217 - 225 (2012)
A new simple approach to the synthesis of unsymmetrical ureas HetNC(O)NRR′ (HetNH = pyrrole, indole, carbazole; R, R′ = H, alkyl, aryl) has been explored, which involves the direct reaction of the N-phenoxycarbonyl derivatives of pyrrole, indole and carba
