Check Digit Verification of cas no

The CAS Registry Mumber 74402-21-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,4,0 and 2 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 74402-21:
(7*7)+(6*4)+(5*4)+(4*0)+(3*2)+(2*2)+(1*1)=104
104 % 10 = 4
So 74402-21-4 is a valid CAS Registry Number.

PHOTO-INDUCED REACTION OF ALKYLATED 1,4-TOLUQUINONE CARRYING ESTER GROUP IN THE ALKYL SIDE CHAIN

Maruyama, Kazuhiro,Kozuka, Tadashi

, p. 341 - 342 (1980)

Irradiation of several 1,4-toluquinones 1a-d having functionalized side chain rapidly gave bicyclic phenolic compounds 2a-d in good yields via intramolecular hydrogen abstraction-proton transfercyclization.In the case of 1f, however, it was found that int
