Check Digit Verification of cas no

The CAS Registry Mumber 220437-87-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,4,3 and 7 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 220437-87:
(8*2)+(7*2)+(6*0)+(5*4)+(4*3)+(3*7)+(2*8)+(1*7)=106
106 % 10 = 6
So 220437-87-6 is a valid CAS Registry Number.

Oxidation and rearrangement of 5-substituted 5- ethoxycarbonyl[1,2,4]triazolidine-3-thiones

Schantl, Joachim G.,Lang, Sergius,Wurst, Klaus

, p. 251 - 258 (2007/10/03)

The reaction of ethyl 2-(phenylhydrazono)alkanoates (1) with potassium thiocyanate in acetic acid affords 5-ethoxycarbonyl-substituted [1,2,4]triazolidine-3-thiones (3). Oxidation (KMnO4) converts 3 into 1- ethoxycarbonyl-2,3-dihydro-1H-[1,2,4]
