Check Digit Verification of cas no

The CAS Registry Mumber 119241-43-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,2,4 and 1 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 119241-43:
(8*1)+(7*1)+(6*9)+(5*2)+(4*4)+(3*1)+(2*4)+(1*3)=109
109 % 10 = 9
So 119241-43-9 is a valid CAS Registry Number.

1'-Derivatives of Sucrose and Their Acid Hydrolysis

Guthrie, R. D. (Gus),Jenkins, Ian D.,Watters, James J.

, p. 2487 - 2497 (2007/10/02)

Syntheses of 1'-chloro-1'-deoxy- and 1'-deoxy-sucrose are described.Several routes were investigated, the most successful being through 6,1',6'-tri-O-(2,4,6-trimethylbenzenesulfonyl)sucrose.Attempts to prepare 1'-deoxy-1'-fluorosucrose were unsuccessful.The rates of the acid-catalysed hydrolysis of 1'-chloro-1'-deoxysucrose and of 1'-deoxysucrose have been measured.These values are compared with that for sucrose itself.The mechanism of the hydrolyses is discussed.
