Check Digit Verification of cas no

The CAS Registry Mumber 139512-86-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,5,1 and 2 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 139512-86:
(8*1)+(7*3)+(6*9)+(5*5)+(4*1)+(3*2)+(2*8)+(1*6)=140
140 % 10 = 0
So 139512-86-0 is a valid CAS Registry Number.

SYNTHESE ET ETUDE DE LA DEGRADATION PHOTOCHIMIQUE DE TENSIO-ACTIFS CATIONIQUES PHOTOCLIVABLES

Strub-Leconte, M. P.,Riess, G.

, p. 137 - 144 (2007/10/02)

A homologous series of photocleavable cationic surfactants was prepared.These aryl-alkyl-ketone type surfactants have the following structure .Their critical micelle concentration in water was determined.The photodegradation study has shown that the cleavage occurs with a high quantum yield by a Norrish II mechanism with formation of alkene, substituted acetophenone and cyclobutanols.The photochemical yield of cleavage reaches 75 percent with formation of a hydrophilic (substituted acetophenone) and a hydrophobic derivative (alkene).
