87506-04-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 87506-04-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,5,0 and 6 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 87506-04:
(7*8)+(6*7)+(5*5)+(4*0)+(3*6)+(2*0)+(1*4)=145
145 % 10 = 5
So 87506-04-5 is a valid CAS Registry Number.

Synthesis of cis-Jasmone via the Retroaldol-aldol Condensation of 3-(cis-3-hexenyl)-2-cyclopentenone in an Autoclave

Yoshida, Takashi,Saito, Shojiro

, p. 3931 - 3932 (1982)

cis-Jasmone was efficiently synthesized from 2-cyclopentenone.The treatment of cyclopentenone with sodium p-toluenesulfinate gave 3-(p-tolylsulfonyl)cyclopentanone in a 92.5percent yield.The alkylation of the sulfone, after the protection of the ketone, with cis-1-bromo-3-hexene, followed by desulfonylation with 5percent hydrochloric acid in tetrahydrofuran, afforded 3-(cis-3-hexenyl)-2-cyclopentenone in a good yield.The retroaldol-aldol condensation of the cyclopentenone in a stainless steel autoclave in presence of 5percent sodium hydroxide yielded cis-jasmone in a 80percent yield.
