Check Digit Verification of cas no

The CAS Registry Mumber 1204307-27-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,4,3,0 and 7 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1204307-27:
(9*1)+(8*2)+(7*0)+(6*4)+(5*3)+(4*0)+(3*7)+(2*2)+(1*7)=96
96 % 10 = 6
So 1204307-27-6 is a valid CAS Registry Number.

supporting information; experimental part, p. 54 - 55 (2010/03/25)

(Chemical Equation Presented) A denitrogenative annulation reaction of 1,2,3-benzotriazin-4(3H)-ones with allenes catalyzed by a nickel-phosphine complex to produce a variety of substituted 3,4-dihydroisoquinolin-1(2H)-ones in a regioselective manner is described. A highly enantioselective version, as well as structural evidence for the mechanistic course of this reaction, is also presented.
