Check Digit Verification of cas no

The CAS Registry Mumber 126579-99-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,5,7 and 9 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 126579-99:
(8*1)+(7*2)+(6*6)+(5*5)+(4*7)+(3*9)+(2*9)+(1*9)=165
165 % 10 = 5
So 126579-99-5 is a valid CAS Registry Number.

Azomethine ylide generation via the dipole cascade

Padwa, Albert,Dean, Dennis C.,Hertzog, Donald L.,Nadler, William R.,Zhi, Lin

, p. 7565 - 7580 (2007/10/02)

A series of N-acyl 2-diazo-3-oxobutanoates, when treated with a catalytic quantity of a rhodium(II) carboxylate, were found to afford substituted pyrroles derived from an azomethine ylide intermediate. The initial reaction involves generation of the expec
