Check Digit Verification of cas no

The CAS Registry Mumber 1313759-73-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,3,7,5 and 9 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1313759-73:
(9*1)+(8*3)+(7*1)+(6*3)+(5*7)+(4*5)+(3*9)+(2*7)+(1*3)=157
157 % 10 = 7
So 1313759-73-7 is a valid CAS Registry Number.

Construction of chiral quaternary carbon center via catalytic asymmetric aza-Henry reaction with α-substituted nitroacetates

Li, Minghua,Ji, Nan,Lan, Ting,He, Wei,Liu, Rui

, p. 20346 - 20350 (2014)

The catalytic enantioselective aza-Henry reaction of N-Boc aldimines 2 and 2-nitropropionic acid ethyl ester 3 in the mixed solvents of toluene-saturated brine (10:1) was catalyzed by cinchona quaternary ammonium salts to form a new quaternary carbon center. High yields (up to 90%), and excellent enantioselectivities (up to 99% ee) and diastereoselectivity ratio (up to 22:1) were successfully obtained with mild conditions. This journal is the Partner Organisations 2014.
