Check Digit Verification of cas no
The CAS Registry Mumber 83095-28-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,0,9 and 5 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 83095-28:
(7*8)+(6*3)+(5*0)+(4*9)+(3*5)+(2*2)+(1*8)=137
137 % 10 = 7
So 83095-28-7 is a valid CAS Registry Number.

ON THE MECHANISM OF THE LEWIS ACID CATALYZED CYCLOCONDENSTION OF ALDEHYDES WITH SILOXYDIENES
Larson, Eric R.,Danishefsky, Samuel
, p. 1975 - 1978 (2007/10/02)
Competing cycloaddition versus aldolization-cyclization processes are demonstrated in the formation of 6-styryl-5,6-dihydro-γ-pyrone via the BF3 catalyzed reaction of cinnamaldehyde with trans-1-methoxy 3-trimethylsilyloxy-1,3-butadiene.
