102689-56-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 102689-56-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,2,6,8 and 9 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 102689-56:
(8*1)+(7*0)+(6*2)+(5*6)+(4*8)+(3*9)+(2*5)+(1*6)=125
125 % 10 = 5
So 102689-56-5 is a valid CAS Registry Number.

4-Aidobutyryl Group for Temporary Protection of Hydroxyl Functions
Kusumoto, Shoichi,Sakai, Keiichiro,Shiba, Tetsuo
, p. 1296 - 1298 (2007/10/02)
4-Azidobutyryl esters formed from hydroxyl compounds and 4-azidobutyryl chloride were shown to be cleaved via reduction to 4-aminobutyrate followed by intramolecular O->N-acyl migrations to regenerate the free hydroxyl groups.High susceptibility of aide g
