91763-93-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 91763-93-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,7,6 and 3 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 91763-93:
(7*9)+(6*1)+(5*7)+(4*6)+(3*3)+(2*9)+(1*3)=158
158 % 10 = 8
So 91763-93-8 is a valid CAS Registry Number.

IMPROVED SYNTHESIS OF (+/-)-AR-TURMERONE VIA ORGANOTIN REAGENTS
Duchene, Alain,Quintard, Jean-Paul
, p. 873 - 882 (2007/10/02)
(+/-)-Ar-turmerone has been obtained alternatively from p-methylacetophenone and p-bromotoluene with ethoxymethyltributyltin of α-ethoxycrotyltributyltin and isobutenyltributyltin as key reagents.The overall yields lie in the range 49-60percent.
