Check Digit Verification of cas no

The CAS Registry Mumber 393536-67-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,9,3,5,3 and 6 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 393536-67:
(8*3)+(7*9)+(6*3)+(5*5)+(4*3)+(3*6)+(2*6)+(1*7)=179
179 % 10 = 9
So 393536-67-9 is a valid CAS Registry Number.

Asymmetric synthesis of protected 1,2-amino alcohols using tert-butanesulfinyl aldimines and ketimines

Tang,Volkman,Ellman

, p. 8772 - 8778 (2007/10/03)

tert-Butanesulfinyl aldimines and ketimines bearing an α-benzyloxy or α-silyloxy substituent serve as precursors in the synthesis of protected 1,2-amino alcohols in high yields and diastereoselectivities. General protocols are described for the addition of unbranched alkyl, branched alkyl, and aryl organometallic reagents to N-sulfinyl aldimines 1 and 2 and ketimines 5 and 6. Furthermore, the selective N- or O-deprotection of sulfinamide products 3, 4, 7, and 8 is described, enabling further synthetic transformations of the reaction products.
