Check Digit Verification of cas no

The CAS Registry Mumber 87634-34-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,6,3 and 4 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 87634-34:
(7*8)+(6*7)+(5*6)+(4*3)+(3*4)+(2*3)+(1*4)=162
162 % 10 = 2
So 87634-34-2 is a valid CAS Registry Number.

Iron(III) catalysed synthesis of unsymmetrical di and trisubstituted ureas - A variation of classical Ritter reaction

Basavaprabhu, Hosamani,Sureshbabu, Vommina V.

supporting information; experimental part, p. 2528 - 2533 (2012/04/23)

An application of the classical Ritter reaction for the synthesis of unsymmetrical di and trisubstituted ureas catalyzed by FeCl3 is described. The protocol is of significant interest in view of the easy availability of precursors, mild reaction conditions employed and interestingly its applicability for the alkylation of alcohols capable of forming stable carbocationic intermediates even to the sterically hindered moieties.
