Check Digit Verification of cas no

The CAS Registry Mumber 185197-89-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,5,1,9 and 7 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 185197-89:
(8*1)+(7*8)+(6*5)+(5*1)+(4*9)+(3*7)+(2*8)+(1*9)=181
181 % 10 = 1
So 185197-89-1 is a valid CAS Registry Number.

Ozonides of mono-, bi- and tricyclic terpenes

Griesbaum, Karl,Hilss, Michael,Bosch, Joachim

, p. 14813 - 14826 (1996)

Ozonolysis of (+)-limonene (1) afforded a monoozonide 2 by attack of ozone at the internal double bond and two diastereomeric diozonides (3). Ozonolysis of 1 on polyethylene gave diozonides 3, and ozonolysis on silica gel gave an epoxy ozonide 5. Ozonolyses of (-)-β-pinene (15), (+)-sabinene (20) and (+)-aromadendrene (23) gave two diastereomers, each, of the corresponding ozonides 16, 21 and 24, respectively. Ozonolysis of camphene (26) gave a very labile ozonide 27, while ozonolysis of (-)-α-pinene (12) gave no ozonide. Ozonolysis of (+)-limonene (1) in the presence of formaldehyde gave a cross-ozonide (4), derived from ozone cleavage of the internal double bond, and ozonolysis of (-)-β-pinene in the presence of acetaldehyde also gave a cross-ozonide (17).
