Check Digit Verification of cas no
The CAS Registry Mumber 63542-37-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,3,5,4 and 2 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 63542-37:
(7*6)+(6*3)+(5*5)+(4*4)+(3*2)+(2*3)+(1*7)=120
120 % 10 = 0
So 63542-37-0 is a valid CAS Registry Number.

Synthesis of 7,8-Dihydroxy-5-hydroxymethyl-2-phenyl-chroman-4-one; the Aglycon of Actinoflavoside

, p. 116 - 118 (2007/10/03)
The first synthesis of 7,8-dihydroxy-5-hydroxymethyl-2-phenyl-chroman-4- one, the aglycon part of a new-type glucoside, actinoflavoside, was accomplished. The regioselective oxidation of the methyl group at the 5-position in 7,8-dihydroxy-5-methyl-2-phenyl-chroman-4-one derived from 3,4,5-trimethoxytoluene was performed by use of ammonium cerium(VI) nitrate (CAN).
