Check Digit Verification of cas no

The CAS Registry Mumber 281199-44-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,1,1,9 and 9 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 281199-44:
(8*2)+(7*8)+(6*1)+(5*1)+(4*9)+(3*9)+(2*4)+(1*4)=158
158 % 10 = 8
So 281199-44-8 is a valid CAS Registry Number.

Palladium-catalyzed hydrophosphorylation of allenes leading to regio- and stereoselective formation of allylphosphonates

Zhao, Chang-Qiu,Han, Li-Biao,Tanaka, Masato

, p. 4196 - 4198 (2000)

Hydrophosphorylation of allenes was catalyzed by palladium complexes, leading to the regio- and stereoselective formation of allylphosphonates. Hydrophosphorylation of allenes, catalyzed by palladium complexes, offered a convenient and clean route to allylphosphonates. Utility of allylphosphonates was established as intermediates in stereoselective synthesis.
