Check Digit Verification of cas no

The CAS Registry Mumber 141839-26-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,1,8,3 and 9 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 141839-26:
(8*1)+(7*4)+(6*1)+(5*8)+(4*3)+(3*9)+(2*2)+(1*6)=131
131 % 10 = 1
So 141839-26-1 is a valid CAS Registry Number.

Lithium Alkylamide-Catalyzed Addition Reaction of Alkylamines to Vinyl Monomers. III. Addition Reaction of p-Substituted Benzylamines to Styrene and Divinylbenzenes

Hamana, Hiroshi,Iwasaki, Fuminori,Nagashima, Hiroyoshi,Hattori, Kazuhisa,Hagiwara, Tokio,Narita, Tadashi

, p. 1109 - 1113 (2007/10/02)

The lithium alkylamide-catalyzed addition reaction of p-substituted benzyamines with m- and p-divinylbenzene was examined in order to synthesize new styrene derivatives.Though divinylbenzene possesses two vinyl groups, 1:1 adducts, the N-(p-substituted benzyl)vinylphenethylamines (6, 8) were found to be prepared selectively.The reaction with styrene was also examined as a model reaction.From kinetic studies, the Hammett ρ values for the addition reaction of p-substituted benzylamines to the styrene, m-divinylbenzene and p-divinylbenzene, were -0.72, -0.67, and -1.1, respectively, at 50 deg C.
