Uses
4-Methoxyphenyl 4-O-Acetyl-3,6-di-O-benzyl-2-deoxy-2-phthalimido-beta-D-glucopyranoside (CAS# 140615-77-6) is a useful building block used in the preparation of chitooligosaccharides as plant growth inhibitors, antimicrobials, and antineoplastics.
Check Digit Verification of cas no
The CAS Registry Mumber 140615-77-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,6,1 and 5 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 140615-77:
(8*1)+(7*4)+(6*0)+(5*6)+(4*1)+(3*5)+(2*7)+(1*7)=106
106 % 10 = 6
So 140615-77-6 is a valid CAS Registry Number.

Use of methanesulfonic acid in the reductive ring-opening of O-benzylidene acetals
Zinin, Alexander I.,Malysheva, Nelly N.,Shpirt, Anna M.,Torgov, Vladimir I.,Kononov, Leonid O.
, p. 627 - 630 (2008/03/13)
Methanesulfonic acid was shown to be an efficient and convenient substitute for ethereal HCl in reductive 4,6-O-benzylidene acetal ring-opening reaction with sodium cyanoborohydride in THF. Normal regioselectivity was observed, the 6-O-benzyl ethers with
