858617-49-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 858617-49-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,8,6,1 and 7 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 858617-49:
(8*8)+(7*5)+(6*8)+(5*6)+(4*1)+(3*7)+(2*4)+(1*9)=219
219 % 10 = 9
So 858617-49-9 is a valid CAS Registry Number.

A facile regioselective decomposition of tosylhydrazones: An application towards the synthesis of α-lipoic acid
Chavan, Subhash P.,Kale, Ramesh R.,Pasupathy
, p. 1129 - 1132 (2007/10/03)
A facile regioselective decomposition of tosylhydrazones using NaOH as a base in refluxing isopropyl alcohol is described. This finding has been successfully applied towards the synthesis of (±)-α-lipoic acid (1).
