Check Digit Verification of cas no

The CAS Registry Mumber 952688-02-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,5,2,6,8 and 8 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 952688-02:
(8*9)+(7*5)+(6*2)+(5*6)+(4*8)+(3*8)+(2*0)+(1*2)=207
207 % 10 = 7
So 952688-02-7 is a valid CAS Registry Number.

Rhodium(I)-catalyzed intramolecular hydroacylation of 4,6-dienals: Novel synthesis of cycloheptenones

Oonishi, Yoshihiro,Mori, Miwako,Sato, Yoshihiro

, p. 2323 - 2336 (2008/02/13)

Rhodium(I)-catalyzed hydroacylation of 4,6-dienals was investigated. Hydroacylation of 4,6-dienals with a substituent at the C7 position produced cycloheptenone derivatives as the major products, while the cyclization of 4,6-dienals with no substituent at the terminus of the diene moiety preferentially gave cyclopentanone derivatives. The olefinic geometry of the diene moiety in 4,6-dienals also affected the reaction course, and the cyclization of substrates with an E-olefin at the C6 position produced cycloheptenone derivatives as the major products, while a cyclopentanone derivative was obtained from a substrate with a Z-olefin at the C6 position.
