Check Digit Verification of cas no

The CAS Registry Mumber 288582-12-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,8,5,8 and 2 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 288582-12:
(8*2)+(7*8)+(6*8)+(5*5)+(4*8)+(3*2)+(2*1)+(1*2)=187
187 % 10 = 7
So 288582-12-7 is a valid CAS Registry Number.

A Versatile Synthesis of α-Amino Acid Derivatives via the Ugi Four-Component Condensation with a Novel Convertible Isonitrile

Rikimaru, Kentaro,Yanagisawa, Arata,Kan, Toshiyuki,Fukuyama, Tohru

, p. 41 - 44 (2004)

The Ugi four-component condensation (4CC) reaction with the carbonate-type isonitrile 9 proceeded smoothly, and subsequent base treatment of the Ugi products 10 provided the N-acyloxazolidinones 11 in high yield. The N-acyloxazolidinones derivatives can be reacted with several hetero-nucleophiles, namely, reaction of 11 with thiolates gave thiol ester derivatives 16 efficiently.
