Check Digit Verification of cas no

The CAS Registry Mumber 1204139-30-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,4,1,3 and 9 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1204139-30:
(9*1)+(8*2)+(7*0)+(6*4)+(5*1)+(4*3)+(3*9)+(2*3)+(1*0)=99
99 % 10 = 9
So 1204139-30-9 is a valid CAS Registry Number.

Synthetic routes to pyrrolizine-1,5-dione derivatives by flash vacuum pyrolysis of amidomethylene derivatives of Meldrum's acid

McNab, Hamish,Morrow, Mark,Parsons, Simon,Shannon, David A.,Withell, Kirsti

, p. 4936 - 4942 (2009)

Methoxymethylene Meldrum's acid 1 reacts with 5- and 6-membered lactams in refluxing acetonitrile to give the N-substituted products 9-15. If the reactions are continued for extended times, the Meldrum's acid derivatives decompose to provide enamidoesters
