Check Digit Verification of cas no

The CAS Registry Mumber 590365-63-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,9,0,3,6 and 5 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 590365-63:
(8*5)+(7*9)+(6*0)+(5*3)+(4*6)+(3*5)+(2*6)+(1*3)=172
172 % 10 = 2
So 590365-63-2 is a valid CAS Registry Number.

Tandem reduction-olefination of triethyl 2-acyl-2-fluoro-2-phosphonoacetates and a synthetic approach to Cbz-Gly-Ψ[(Z)-CF{double bond, long}C]-Gly dipeptide isostere

, p. 11881 - 11890 (2007/10/03)

(Z)-α-Fluoro-α,β-unsaturated esters (Z)-7a-f were stereoselectively prepared by a tandem reduction-olefination of triethyl 2-acyl-2-fluoro-2-phosphonoacetates 6a-f with NaBH4 in EtOH. A concise synthesis of Cbz-Gly-Ψ[(Z)-CF{double bond, long}C]-Gly (26) as a dipeptide isostere was achieved via the tandem reduction-olefination of the corresponding 2-acyl-2-fluoro-2-phosphonoacetate 20.
