133951-65-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 133951-65-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,9,5 and 1 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 133951-65:
(8*1)+(7*3)+(6*3)+(5*9)+(4*5)+(3*1)+(2*6)+(1*5)=132
132 % 10 = 2
So 133951-65-2 is a valid CAS Registry Number.

Synthesis of trans-4-alkenyloxazoles
Zhao,Scarlato,Armstrong
, p. 1609 - 1612 (2007/10/02)
Oxazoles with trans-4-alkenyl substituents were synthesized using a Wittig condensation of the corresponding tri-n-butylphosphonium ylids with aldehydes. The resulting 4-alkenyloxazoles were obtained with greater than 95% trans selectivity.
