Check Digit Verification of cas no
The CAS Registry Mumber 132333-97-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,3,3 and 3 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 132333-97:
(8*1)+(7*3)+(6*2)+(5*3)+(4*3)+(3*3)+(2*9)+(1*7)=102
102 % 10 = 2
So 132333-97-2 is a valid CAS Registry Number.

Preparation and catalytic hydrogenation of 1,2,4-oxadiazolo[4,5-a]indolines
Malamidou-Xenikaki,Coutouli-Argyropoulou
, p. 7865 - 7872 (1990)
2,3,3-Trimethyl-3H-indole 1 reacts with nitrile oxides 2 to afford 1,2,4-oxadiazolo [4,5-a]indolines 3 in high yields. Catalytic hydrogenation of compounds 3 over Raney nicke results in the cleavage of the oxadiazole ring and gives almost quantitatively products 4 or 5.
