Check Digit Verification of cas no

The CAS Registry Mumber 57738-18-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,7,3 and 8 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 57738-18:
(7*5)+(6*7)+(5*7)+(4*3)+(3*8)+(2*1)+(1*8)=158
158 % 10 = 8
So 57738-18-8 is a valid CAS Registry Number.

BASIC MEDIA BEHAVIOR OF N- ETHYL CARBAMATES (Y=SMe, SOMe, SO2Me, H, Br, CN)

Ruano, Jose Luis Garcia,Pedregal, Concepcion,Rodriguez, Jesus H.

, p. 203 - 214 (1989)

From the results obtained in the hydrolysis reaction of the carbamate group of some thioderivatives compounds whose common structure is (2-EtOOCNH-C6H4)-CHOH-CH2Y a mechanism is suggested to explain the products, as well as the relationship between the relative configuration of diastereoisomeric sulfoxides (Y=SOMe) with the reaction rate and with the stereochemical outcome.Other interesting and unexpected products are yielded when the hydrolysis reaction of other carbamates (Y=H, Br, CN) is carried out.In the present cases, the carbamate function seems to behave as a very versatile group capable of readily undergoing conversions to several kinds of heterocycles.
