135441-49-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 135441-49-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,4,4 and 1 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 135441-49:
(8*1)+(7*3)+(6*5)+(5*4)+(4*4)+(3*1)+(2*4)+(1*9)=115
115 % 10 = 5
So 135441-49-5 is a valid CAS Registry Number.

PREPARATION AND CHARACTERIZATION OF 1-ARYLAZO-SUBSTITUTED NAPHTHYLSULFIDES
Schulze, Margit,Hartmann, Horst
, p. 161 - 171 (2007/10/02)
By reaction of 2-chloro- and 4-chloro-1-arylazo-naphthalenes 3 and 4 with mercaptides in a dipolar aprotic solvent, stable 1-arylazo-substituted 2- and 4-naphthylsulfides 5 and 6, resp., are formed.The hitherto unknown compounds are deeply coloured and, i
