Check Digit Verification of cas no
The CAS Registry Mumber 178961-20-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,8,9,6 and 1 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 178961-20:
(8*1)+(7*7)+(6*8)+(5*9)+(4*6)+(3*1)+(2*2)+(1*0)=181
181 % 10 = 1
So 178961-20-1 is a valid CAS Registry Number.

PROCESS FOR PREPARING AMINES AND A CARBOXAMIDE THEREOF
-
Page/Page column 23, (2010/02/15)
Chiral, secondary amines of the formula (I) or (II), where R01, R02 and R03 are each, independently of one another, C1-C4-alkyl, R04 is C1-C4-alkyl, C1-C4-alkoxymethyl or C1-C4-alkoxyethyl, and * indicates predominantly one configurational isomer, can be obtained by hydrogenation of corresponding ketimines in the presence of iridium complexes with chiral ferrocene tetraphosphines in which a secondary phosphine group and 1-secondary phosphinalk-1-yl are bound to each cyclopentadienyl ring in ortho positions.
ENANTIOSELECTIVE SYNTHESIS OF OPTICALLY ACTIVE METOLACHLOR VIA ASYMMETRIC REDUCTION
Cho, Byung Tae,Chun, Yu Sung
, p. 337 - 340 (2007/10/02)
Optically active metolachlor was prepared by chloroacetylation of the corresponding amine obtained by asymmetric reduction of the requisite imine with the chiral hydrides, such as Itsuno's reagent (4), Corey's reagent (5) and K glucoride (6).
