The CAS Registry Mumber 70265-69-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,2,6 and 5 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 70265-69:
(7*7)+(6*0)+(5*2)+(4*6)+(3*5)+(2*6)+(1*9)=119
119 % 10 = 9
So 70265-69-9 is a valid CAS Registry Number.

NOVEL AND SELECTIVE SYNTHESES OF NEW ANALOGUES OF PRECOCENE-2 AND PRECOCENE-3 CONTAINING 5-METHYL- OR 8-METYL-SUBSTITUENTS

Timar, Tibor,Seboek, Peter,Eszenyi, Tibor,Jaszberenyi, Joseph Cs.

, p. 2719 - 2728 (2007/10/02)

New analogues of precocene-2 and precocene-3 containing 5-methyl- or 8-methyl-substituents have been synthesised in good yields utilising regioselective O-alkylation of 6,7-dihydroxy-2,2,5-trimethyl-4-chromanone and 6,7-dihydroxy-2,2,8-trimethyl-4-chromanone as the key step.
