Check Digit Verification of cas no

The CAS Registry Mumber 70298-94-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,2,9 and 8 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 70298-94:
(7*7)+(6*0)+(5*2)+(4*9)+(3*8)+(2*9)+(1*4)=141
141 % 10 = 1
So 70298-94-1 is a valid CAS Registry Number.

A Convenient Synthesis of Condensed Cyclopentane System. Annelation by Intramolecular 1,3-Dipolar Addition of Nitrones

Takahashi, Satoru,Kusumi, Takenori,Sato, Yoko,Inouye, Yoshinobu,Kakisawa, Hiroshi

, p. 1777 - 1780 (1981)

Intramolecular 1,3-dipolar addition reactions of nitrones were investigated.Four alkenyl nitrones were studied: 2-allyl-, 2-(3-butenyl)-, 2-(4-pentenyl)-, and 2-(9-decenyl)-N-methylcyclohexanimine N-oxides.Among these, 2-(3-butenyl)-N-methylcyclohexanimine N-oxide was found to cyclize most smoothly, giving a perhydroindene derivative as a single regio- and stereoisomer.A perhydroazulene derivative was obtained by cyclization of 2-(3-butenyl)-N-methylcycloheptanimine N-oxide.
