Check Digit Verification of cas no

The CAS Registry Mumber 1224244-74-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,4,2,4 and 4 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1224244-74:
(9*1)+(8*2)+(7*2)+(6*4)+(5*2)+(4*4)+(3*4)+(2*7)+(1*4)=119
119 % 10 = 9
So 1224244-74-9 is a valid CAS Registry Number.

Acyl radical insertion for the direct formation of new seven-substituted pterin analogs

Pruet, Jeff M.,Robertus, Jon D.,Anslyn, Eric V.

, p. 2539 - 2540 (2010)

A variety of pterin molecules were synthesized via an under-utilized acyl radical insertion, using aldehydes and α-keto esters as the acyl source. These reactions gave complete regiospecificity for the 7-isomer, with reaction times ranging in minutes, often with instantaneous product precipitation. This approach led to the construction of new pterin analogs unaccessible via traditional Friedel-Crafts acylation. The compounds were characterized by NMR spectroscopy and high-resolution mass spectroscopy.
