Check Digit Verification of cas no

The CAS Registry Mumber 132782-91-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,7,8 and 2 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 132782-91:
(8*1)+(7*3)+(6*2)+(5*7)+(4*8)+(3*2)+(2*9)+(1*1)=133
133 % 10 = 3
So 132782-91-3 is a valid CAS Registry Number.

1,3-Dipolar Cycloaddition Reactions of 1,4-Benzoquinones with Nitrilimines

Argyropoulos, N. G.,Mentzafos, D.,Terzis, A.

, p. 1983 - 1988 (2007/10/02)

The cycloaddition reactions of some aryl conjugated p-benzoquinones with nitrilimines were studied.Depending upon the reaction conditions mono- and/or bis- adducts were isolated only from carbon-carbon double bond.The structure determination was unequivocally established by an X-ray analysis carried out on a bis-adduct.The observed regio-, as well as site-selectivity was qualitatively correlated with frontier molecular orbitals of the reacting species.
