263772-24-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 263772-24-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,3,7,7 and 2 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 263772-24:
(8*2)+(7*6)+(6*3)+(5*7)+(4*7)+(3*2)+(2*2)+(1*4)=153
153 % 10 = 3
So 263772-24-3 is a valid CAS Registry Number.

REGIOSELECTIVITY IN CATALYTIC CYCLOPROPANATION REACTIONS
Doyle, Michael P.,Dorow, Roberta L.,Tamblyn, William H.,Buhro, William E.
, p. 2261 - 2264 (2007/10/02)
Regioselectivities of cyclopropanation reactions with ethyl diazoacetate and monosubstituted dienes correlate linearly with the reaction catalyst and provide definition of the "metal carbene regioselectivity index".
