91664-14-1 Usage

Preparation

Preparation by condensation of gallacetophenone with 1,3-butadiene in the presence of 85% orthophosphoric acid in xylene at 30–35° (60%).

Check Digit Verification of cas no

The CAS Registry Mumber 91664-14-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,6,6 and 4 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 91664-14:
(7*9)+(6*1)+(5*6)+(4*6)+(3*4)+(2*1)+(1*4)=141
141 % 10 = 1
So 91664-14-1 is a valid CAS Registry Number.

A FACILE SYNTHESIS OF CROTYLACETOPHENONES AND ACETYL SUBSTITUTED 2-METHYLCHROMANS

Ahluwalia, V. K.,Singh, Manjula,Singh, R. P.

, p. 126 - 138 (2007/10/02)

Condensation of hydroxyacetophenones with but-1,3-diene has been achieved in presence of orthophosphoric acid leading to the formation of crotyl acetophenones which were cyclised to the corresponding 2-methylchromans.
