63603-75-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 63603-75-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,3,6,0 and 3 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 63603-75:
(7*6)+(6*3)+(5*6)+(4*0)+(3*3)+(2*7)+(1*5)=118
118 % 10 = 8
So 63603-75-8 is a valid CAS Registry Number.

Tosyl Group Transfer with O,O'-Ditosylethyleneglycol
Weber, Edwin
, p. 1551 - 1553 (2007/10/02)
The ability of O,O'-ditosylethyleneglycol (2a) to act as tosyl group transfer reagent to neopentyl type alcohols is described.Starting from 1a the spirooxetane 3 can be synthesized via tosyl group transfer in high yield. 4a by double tosyl transfer yields
