Check Digit Verification of cas no

The CAS Registry Mumber 98944-74-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,9,4 and 4 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 98944-74:
(7*9)+(6*8)+(5*9)+(4*4)+(3*4)+(2*7)+(1*4)=202
202 % 10 = 2
So 98944-74-2 is a valid CAS Registry Number.

Stereocontrolled Synthesis of a Polyether Fragment

Bartlett, Paul A.,Holm, Kjetil H.,Morimoto, Akira

, p. 5179 - 5183 (2007/10/02)

A sequence utilizing selenolactonization of olefinic acid 4, Ireland-Claisen rearrangement of ketal ester 9, iodolactonization / epoxidation of olefinic acid 10, and regioselective hydrolysis of epoxide 15b is described for the stereocontrolled conversion of meso-2,4-dimethylglutaric anhydride to racemic tetrahydropyran lactone 1.
