Check Digit Verification of cas no

The CAS Registry Mumber 87017-89-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,0,1 and 7 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 87017-89:
(7*8)+(6*7)+(5*0)+(4*1)+(3*7)+(2*8)+(1*9)=148
148 % 10 = 8
So 87017-89-8 is a valid CAS Registry Number.

Chemical Modification of Maltose. VI. Selective p-Toluenesulfonylation of 1,6-Anhydro-4',6'-O-benzylidene-β-maltose using Phase Transfer Catalysis

Mori, Masami,Tejima, Setsuzo

, p. 1382 - 1384 (2007/10/02)

Treatment of 1,6-anhydro-4',6'-O-benzylidene-β-maltose (1) in dichloromethane with 1.2 eq of tosyl chloride in the presence of tetrabutylammonium hydrogen sulfate and 4 percent sodium hydroxide gave the corresponding 2'-O-tosylate (5) as the main product
