Check Digit Verification of cas no

The CAS Registry Mumber 121687-16-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,6,8 and 7 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 121687-16:
(8*1)+(7*2)+(6*1)+(5*6)+(4*8)+(3*7)+(2*1)+(1*6)=119
119 % 10 = 9
So 121687-16-9 is a valid CAS Registry Number.

ASYMMETRIC ALDOL REACTION OF α-ISOCYANOACETAMIDES WITH ALDEHYDES CATALYZED BY A CHIRAL FERROCENYLPHOSPHINE-GOLD(I) COMPLEX

Ito, Yoshihiko,Sawamura, Masaya,Kobayashi,Masaaki,Hayashi, Tamio

, p. 6321 - 6324 (2007/10/02)

Aldol reaction of N,N-dialkyl-α-isocyanoacetamides with primary alkyl aldehydes in the presence of 0.5-1 molpercent of a chiral (aminoalkyl)ferrocenylphosphine-gold(I) catalyst proceeded with high enantio- and diastereoselectivity to give trans-5-alkyl-2-oxazoline-4-carboxamides of up to 98.6percent ee, which were converted into optically active threo-β-hydroxyamino acids.
