Check Digit Verification of cas no

The CAS Registry Mumber 132785-67-2 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 5 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 132785-67:
(8*1)+(7*3)+(6*2)+(5*7)+(4*8)+(3*5)+(2*6)+(1*7)=142
142 % 10 = 2
So 132785-67-2 is a valid CAS Registry Number.

A transannular π-bond pairing approach to the synthesis of 1,3-cyclopentadiene diesters and maleimido-oxepines and a report on their isomerisation

Warrener,Bina,Butler,Pitt,Russell

, p. 7073 - 7076 (1990)

Polycyclobutanoid compounds containing an end-fused 3-membered ring are central to the synthesis of the title target molecules: a new mode for their production is presented. Cyclopentadiene 1,3-diester is isolated and its isomerisation studied. Intermediates supporting the oxygen-walk isomerisation of maleimido-oxepines are isolated.
