Check Digit Verification of cas no

The CAS Registry Mumber 16179-40-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,1,7 and 9 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 16179-40:
(7*1)+(6*6)+(5*1)+(4*7)+(3*9)+(2*4)+(1*0)=111
111 % 10 = 1
So 16179-40-1 is a valid CAS Registry Number.

Facile oxidative hydrolysis of acetals to esters using hypervalent iodine(III)/LiBr combination in water

Panchan, Waraporn,Chiampanichayakul, Supanimit,Snyder, Deanna L.,Yodbuntung, Siriporn,Pohmakotr, Manat,Reutrakul, Vichai,Jaipetch, Thaworn,Kuhakarn, Chutima

experimental part, p. 2732 - 2735 (2010/05/17)

The combination of (diacetoxy)iodobenzene (PhI(OAc)2, DIB) and lithium bromide (LiBr) efficiently oxidized cyclic and acyclic acetals to the corresponding hydroxyalkyl carboxylic esters and simple esters in good to excellent yields. The merits of this reaction are that it employs commercially available and non-explosive hypervalent iodine(III) reagent, water as the solvent, a short reaction time, and mild reaction conditions.

2-Iodoxybenzoic acid/tetraethylammonium bromide/water: An efficient combination for oxidative cleavage of acetals

Kuhakarn, Chutima,Panchan, Waraporn,Chiampanichayakul, Supanimit,Samakkanad, Natthapol,Pohmakotr, Manat,Reutrakul, Vichai,Jaipetch, Thaworn

experimental part, p. 929 - 934 (2009/10/14)

A simple and efficient procedure has been developed for the oxidation of cyclic and acyclic acetals to the corresponding hydroxyalkyl carboxylic esters and simple esters, respectively. 2-Iodoxybenzoic acid (IBX) in the presence of tetraethylammonium bromide was employed for the reaction in aqueous media. The salient features of the protocol include short reaction time, environmentally benign reagents and solvent, and moderate to high yields. Georg Thieme Verlag Stuttgart.
