Check Digit Verification of cas no

The CAS Registry Mumber 142602-50-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,6,0 and 2 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 142602-50:
(8*1)+(7*4)+(6*2)+(5*6)+(4*0)+(3*2)+(2*5)+(1*0)=94
94 % 10 = 4
So 142602-50-4 is a valid CAS Registry Number.

Diastereoselective formation of (Z)-didehydroamino acid esters

Schmidt,Griesser,Leitenberger,Lieberknecht,Mangold,Meyer,Riedl

, p. 487 - 490 (2007/10/02)

The rearrangement of (E)-didehydroamino acid derivatives to the corresponding Z-derivatives under acid or basic catalysis as well as under the influence of radicals has been investigated. The condensation of N-benzyloxycarbonyl or N-tert-butoxycarbonyl protected alkyl 2-amino-2-(dimethoxyphosphoryl)acetates with aldehydes or ketones in dichloromethane in the presence of 1,8-diazabicyclo[5.4.0]undec-7-ene furnishes (Z)-didehydroamino acid ester derivatives diastereoselectively in excellent yields and with high purity.
