Check Digit Verification of cas no

The CAS Registry Mumber 549504-72-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,4,9,5,0 and 4 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 549504-72:
(8*5)+(7*4)+(6*9)+(5*5)+(4*0)+(3*4)+(2*7)+(1*2)=175
175 % 10 = 5
So 549504-72-5 is a valid CAS Registry Number.

Metal carbene-promoted sequential transformations for the enantioselective synthesis of highly functionalized cycloheptadienes

Deng, Liang,Giessert, Anthony J.,Gerlitz, Oksana O.,Dai, Xing,Diver, Steven T.,Davies, Huw M. L.

, p. 1342 - 1343 (2005)

A two-step, three-component coupling of an alkyne, enol ether, and vinyl diazoester was accomplished by use of successive metal carbene-catalyzed transformations. This efficient approach to cycloheptadienes is both diastereo- and enantioselective. Kinetic
