950833-81-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 950833-81-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,5,0,8,3 and 3 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 950833-81:
(8*9)+(7*5)+(6*0)+(5*8)+(4*3)+(3*3)+(2*8)+(1*1)=185
185 % 10 = 5
So 950833-81-5 is a valid CAS Registry Number.

Highly regioselective synthesis of Lndene derivatives including an allene functional group via Pd/C-catalyzed cyclization reaction in air

Bi, Hai-Peng,Liu, Xue-Yuan,Gou, Fa-Rong,Guo, Li-Na,Duan, Xin-Hua,Liangs, Yong-Min

, p. 3527 - 3529 (2007)

lndene derivatives including an aliene functional group are readily prepared in moderate to excellent yields with high regioselectivity under very mild reaction conditions by the Pd/C-catalyzed reaction of propargylic compounds. The resulting products can
