Check Digit Verification of cas no

The CAS Registry Mumber 119995-12-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,9,9 and 5 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 119995-12:
(8*1)+(7*1)+(6*9)+(5*9)+(4*9)+(3*5)+(2*1)+(1*2)=169
169 % 10 = 9
So 119995-12-9 is a valid CAS Registry Number.

SOLID-LIQUID PHASE TRANSFER CATALYTIC SYNTHESIS OF α-AMINO ACID VIA ALKYLATION AND NUCLEOPHILIC ADDITION OF BENZALDEHYDE IMINES

Yaozhong, Jiang,Changyou, Zhou,Shengde, Wu,Daimo, Chen,Youan, Ma,Guilan, Liu

, p. 5343 - 5354 (2007/10/02)

A short, mild and efficient synthetic route of α-amino acid via alkylation, Michael addition and carbonyl addition as well as cycloaddition of aldimines derived from glycine and alanine esters with benzaldehyde under solid-liquid phase transfer catalytic condition has been studied.The key to solid-liquid phase transfer catalyzed reactions is the selection of a base for the various reactants.The yield is dependent on the base used.The results obtained using KOH, K2CO3 and Na2CO3 are discussed.The kinetics of solid-liquid PTC benzylation has been investigated and we propose a possible mechanism of solid-liquid PTC as an interface auto-catalytic procedure.The details of some syntheses of α-amino acids are presented.
