Check Digit Verification of cas no

The CAS Registry Mumber 130714-72-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,7,1 and 4 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 130714-72:
(8*1)+(7*3)+(6*0)+(5*7)+(4*1)+(3*4)+(2*7)+(1*2)=96
96 % 10 = 6
So 130714-72-6 is a valid CAS Registry Number.

Synthesis and resolution of DHCGA, a new conformationally rigid 3,4-dehydroglutamic acid analogue

Trigalo, Francois,Acher, Francine,Azerad, Robert

, p. 5203 - 5212 (2007/10/02)

(±)-1-amino-2-cyclohexene-1,3-dicarboxylic acid (DHCGA),an unsaturated cyclic analogue of glutamic acid, was prepared from 3-carboxy-4-cyclohexenone by a Bucherer-Bergs reaction. Resolution was performed through coupling with L-leucine and separation of the resulting diastereoisomeric dipeptides. Spectral data, including optical rotation and circular dichroism of both enantiomers of DHCGA are reported.
