Check Digit Verification of cas no

The CAS Registry Mumber 120696-32-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,6,9 and 6 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 120696-32:
(8*1)+(7*2)+(6*0)+(5*6)+(4*9)+(3*6)+(2*3)+(1*2)=114
114 % 10 = 4
So 120696-32-4 is a valid CAS Registry Number.

Enynones in Organic Synthesis. 8. Synthesis of the Antimicrobial-Cytotoxic Agent Juncusol and Members of the Effusol Class of Phenols

Jacobi, Peter A.,Kravitz, Joseph I.,Zheng, Wanjun

, p. 376 - 385 (2007/10/02)

Two new syntheses of phenols have been developed which have been utilized in an efficient preparation of the antimicrobial-cytotoxic agent juncusol (22) and several members of the effusol (23) class of phenols.These results complement our earlier studies with enynones of type 42 and provide for the highly efficient conversion of 42 to either methylenecyclopentenones 45 or phenols of type 47 or 54 with virtually 100percent selectivity.
