Check Digit Verification of cas no

The CAS Registry Mumber 125942-85-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,5,9,4 and 2 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 125942-85:
(8*1)+(7*2)+(6*5)+(5*9)+(4*4)+(3*2)+(2*8)+(1*5)=140
140 % 10 = 0
So 125942-85-0 is a valid CAS Registry Number.

Preparation of Enantiomerically Pure Protected 4-Oxo-α-amino Acids and 3-Aryl-α-amino Acids from Serine

Jackson, Richard F. W.,Wishart, Neil,Wood, Anthony,James, Keith,Wythes, Martin J.

, p. 3397 - 3404 (2007/10/02)

The organozinc reagent 13, prepared from the protected β-iodo alanine derivative 3c using ultrasonic activation, is efficiently acylated using acid chlorides in the presence of bis(triphenylphosphine)palladium dichloride to give enantiomerically pure protected 4-oxo-α-amino acids 17 in 39-90percent yield (13 examples).Zinc reagent 13 can also be coupled with aryl iodides in the presence of bis(tri-o-tolylphosphine)palladium dichloride to give enantiomerically pure protected phenylalanine analogues 26, 29, and 30 in 10-67percent yield (11 examples).The reaction tolerates the presence of a variety of functional groups in the acid chloride and the aryl iodide and provides derivatives which can be easily deprotected, at either the carboxyl or amino terminus, to give intermediates suitable for peptide synthesis.
