Check Digit Verification of cas no

The CAS Registry Mumber 141920-90-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,1,9,2 and 0 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 141920-90:
(8*1)+(7*4)+(6*1)+(5*9)+(4*2)+(3*0)+(2*9)+(1*0)=113
113 % 10 = 3
So 141920-90-3 is a valid CAS Registry Number.

REGIOSELECTIVE CYCLOADDITIONS OF 1H-AZEPINE AND 1H-1,2-DIAZEPINE DERIVATIVES WITH N,α-DIPHENYLNITRONE AND NITROSOBENZENE

Saito, Katsuhiro,Yoshino, Akihiro,Watanabe, Hiroyuki,Takahashi, Kensuke

, p. 497 - 504 (2007/10/02)

Reactions of 1-carbomethoxy-1H-azepine with N,α-diphenylnitrone afforded endo- and exo--type cycloadducts in almost the same ratio.Reactions of 1-carboethoxy-1H-azepine with nitrosobenzene in chloroform afforded - and -types of cycloadducts.Analogous results were obtained in the reactions using 1-carboethoxy-1H-1,2-diazepine.
