Check Digit Verification of cas no

The CAS Registry Mumber 125041-75-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,5,0,4 and 1 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 125041-75:
(8*1)+(7*2)+(6*5)+(5*0)+(4*4)+(3*1)+(2*7)+(1*5)=90
90 % 10 = 0
So 125041-75-0 is a valid CAS Registry Number.

UV irradiation of isophorone in presence of allenic esters

Gandhi, R. P.,Ishar, M. P. S.

, p. 381 - 384 (2007/10/02)

Irradiation of a mixture of isophorone and ethyl penta-2,3-dienoate (1a) or ethyl hexa-2,3-dienoate (1b) or ethyl 4-methyl-hexa-2,3-dienoate (1c) in methanol leads to novel addition compounds (2a-c) as major products and cyclobutane-adducts (3a-c) and (4a,b) as minor products.A mechanistic rationale for formation of 2a-c (E geometry around 3,4-double bond) is proffered.
