Check Digit Verification of cas no

The CAS Registry Mumber 118331-44-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,3,3 and 1 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 118331-44:
(8*1)+(7*1)+(6*8)+(5*3)+(4*3)+(3*1)+(2*4)+(1*4)=105
105 % 10 = 5
So 118331-44-5 is a valid CAS Registry Number.

Electrooxidative Cyclization of 4-Dithioazetidinones (Kamiya's Disulfides) A Facile Access to 2-(Substituted methyl)penicillinates

Tanaka, Hideo,Tanaka, Motoaki,Hironaka, Yo-ichi,Nakai, Akira,Torii, Sigeru

, p. 1801 - 1804 (2007/10/02)

A straightforward access to penicillinates bearing SCN and SeCN groups at the 2β-methyl group was performed by electrolysis of 4-dithioazetidinones in a two-phase system (aqueous and organic phases) in the presence of KSCN and KSeCN, respectively, while a mixture of 2β-azidomethyl derivative and its 2α-isomer (6/4) was obtained by a similar electrolysis with NaN3.
