130336-23-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 130336-23-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,3,3 and 6 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 130336-23:
(8*1)+(7*3)+(6*0)+(5*3)+(4*3)+(3*6)+(2*2)+(1*3)=81
81 % 10 = 1
So 130336-23-1 is a valid CAS Registry Number.

One-Pot Synthesis of α-Chloro Ketones from Secondary Alcohols Using N,N-Dichloro-p-toluenesulfonamide
Kim, Yong Hae,Lee, In Sang,Lim, Sang Chul
, p. 1125 - 1128 (2007/10/02)
Various alkyl aryl secondary alcohols reacted with N,N-dichloro-p-toluenesulfonamide (N,N-dichloroamine-T) in CH3CN at 35 deg C to give the corresponding α-chloro ketones in excellent yields under mild and neutral conditions.
