Check Digit Verification of cas no

The CAS Registry Mumber 856219-75-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,6,2,1 and 9 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 856219-75:
(8*8)+(7*5)+(6*6)+(5*2)+(4*1)+(3*9)+(2*7)+(1*5)=195
195 % 10 = 5
So 856219-75-5 is a valid CAS Registry Number.

Kinetic isotope effects in the thermal C2-C6 cyclization of enyne-allenes: Experimental evidence supports a stepwise mechanism

Schmittel, Michael,Vavilala, Chandrasekhar

, p. 4865 - 4868 (2007/10/03)

Kinetic isotope effects suggest that the thermal C2-C 6 cyclization of enyne-allenes proceeds through a stepwise diradical mechanism. This is even true if steric bulk at the alkyne terminus is large, contrary to theoretical predictio
