Check Digit Verification of cas no

The CAS Registry Mumber 677717-56-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,7,7,7,1 and 7 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 677717-56:
(8*6)+(7*7)+(6*7)+(5*7)+(4*1)+(3*7)+(2*5)+(1*6)=215
215 % 10 = 5
So 677717-56-5 is a valid CAS Registry Number.

A new short synthesis of coumestrol and its application for the synthesis of [6,6a,11a-13C3]coumestrol

Al-Maharik, Nawaf,Botting, Nigel P.

, p. 1637 - 1642 (2007/10/03)

A convenient and simple two-step method for the synthesis of coumestrol has been established, which involves a base catalysed condensation of phenyl acetate with benzoyl chloride, followed by demethylation and subsequent tandem intramolecular cyclisation. This method was then employed for the efficient synthesis of multiply 13C-labelled coumestrol.
