121564-15-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 121564-15-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,5,6 and 4 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 121564-15:
(8*1)+(7*2)+(6*1)+(5*5)+(4*6)+(3*4)+(2*1)+(1*5)=96
96 % 10 = 6
So 121564-15-6 is a valid CAS Registry Number.

CYCLIC SULFATES CONTAINIMNG ACID-SENSITIVE GROUPS AND CHEMOSELECTIVE HYDROLYSIS OF SULFATE ESTERS
Kim, B. Moon,Sharpless, K. Barry
, p. 655 - 658 (1989)
Diols containing acid-sensitive functionalities such as acetonide and silyloxy groups are efficiently converted to the corresponding cyclic sulfates via formation of the cyclic sulfites in the presence of a base and oxidation of the isolated sulfites usin
