91212-71-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 91212-71-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,2,1 and 2 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 91212-71:
(7*9)+(6*1)+(5*2)+(4*1)+(3*2)+(2*7)+(1*1)=104
104 % 10 = 4
So 91212-71-4 is a valid CAS Registry Number.

A SIMPLE SYNTHESIS OF DIHYDROJASMONE BY A NOVEL CYCLIZATION OF β,γ-ENONE
Fujisawa, Tamotsu,Sakai, Kunikazu
, p. 55 - 56 (2007/10/02)
Dihydrojasmone was easily synthesized by bromination of 4-methyl-3-pentyl-4-penten-2-one, which was obtained by the alkylation of mesityl oxide, followed by the treatment with a base.
