Check Digit Verification of cas no
The CAS Registry Mumber 100644-82-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,0,6,4 and 4 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 100644-82:
(8*1)+(7*0)+(6*0)+(5*6)+(4*4)+(3*4)+(2*8)+(1*2)=84
84 % 10 = 4
So 100644-82-4 is a valid CAS Registry Number.

ISOPROPYLIDENATION OF L-ARABINOSE N,N-DIMETHYLHYDRAZONE
Koos, Miroslav,Mosher, Harry S.
, p. 1994 - 1999 (2007/10/02)
Direct isopropylidenation of L-arabinose N,N-dimethylhydrazone (I) was studied.Four major products whose structures were proven were produced in varying ratios depending upon the conditions. 2,2-Dimethoxypropane and sulfuric acid at 20 deg C gave a 36percent yield of 2,3:4,5-di-O-isopropylidene-L-arabinose N,N-dimethylhydrazone (II).Attempted aldol condensations directly on this hydrazone with paraformaldehyde were unsuccesful.This hydrazone was readily hydrolyzed to the corresponding protected aldehyde VI which underwent an aldol-Cannizzaro reaction to give the branched chain pentitol VII in high yield.
