Check Digit Verification of cas no

The CAS Registry Mumber 120802-63-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,8,0 and 2 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 120802-63:
(8*1)+(7*2)+(6*0)+(5*8)+(4*0)+(3*2)+(2*6)+(1*3)=83
83 % 10 = 3
So 120802-63-3 is a valid CAS Registry Number.

SUBSTITUENT EFFECTS ON THE PHOTOCHEMISTRY OF o-TOLUALDEHYDES

Charlton, James L.,Koh, Kevin

, p. 5595 - 5598 (2007/10/02)

The effect of 4-oxy and 4,5-dioxy substituents on the photochemical conversion of 2-methylbenzaldehydes to o-quinodimethanes (o-QDMs) has been studied.The presence of a 4-methoxy, or a 4 and 5-methoxy substituent prevented the photochemical formation of the o-QDM whereas 4-acetoxy and 4,5-diacetoxy-2-methylbenzaldehyde and the corresponding mesylates and tosylates were successfully converted to the o-QDMs.
