Check Digit Verification of cas no

The CAS Registry Mumber 670224-89-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,7,0,2,2 and 4 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 670224-89:
(8*6)+(7*7)+(6*0)+(5*2)+(4*2)+(3*4)+(2*8)+(1*9)=152
152 % 10 = 2
So 670224-89-2 is a valid CAS Registry Number.

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

Suzuki, Katsuhiko,Tsuruga, Takeshi,Hiranuma, Kyoko,Yamaura, Masanori

, 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).
