Check Digit Verification of cas no
The CAS Registry Mumber 136705-62-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,7,0 and 5 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 136705-62:
(8*1)+(7*3)+(6*6)+(5*7)+(4*0)+(3*5)+(2*6)+(1*2)=129
129 % 10 = 9
So 136705-62-9 is a valid CAS Registry Number.

Preparation and use of C2-symmetric bis(phospholanes): Production of α-amino acid derivatives via highly enantioselective hydrogenation reactions
Burk, Mark J.,Feaster, John E.,Nugent, William A.,Harlow, Richard L.
, p. 10125 - 10138 (2007/10/02)
A new class of chiral C2-symmetric bis(phospholane) ligands has been prepared and used in rhodium-catalyzed asymmetric hydrogenation reactions. We describe a practical, one-pot procedure which utilizes enantiomerically pure 1,4-diol cyclic sulf
