Check Digit Verification of cas no

The CAS Registry Mumber 134745-40-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,7,4 and 5 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 134745-40:
(8*1)+(7*3)+(6*4)+(5*7)+(4*4)+(3*5)+(2*4)+(1*0)=127
127 % 10 = 7
So 134745-40-7 is a valid CAS Registry Number.

2-OXO-3-BUTENOATE ESTERS AS DIENOPHILES AND THEIR UTILITY IN A NOVEL SYNTHESIS OF PYRROLES

Jacobi, Peter A.,Cai, Guolin

, p. 1765 - 1768 (2007/10/02)

Trisubstituted pyrroles of type 8 have been prepared in a regiospecific fashion by a two step sequence involving Diels-Alder reaction of 2-oxo-3-butenoate esters 1 with 2-alkoxy-1,3-pentadiene derivatives 13, followed by ozonolysis and Paal-Knorr cyclization.
