Check Digit Verification of cas no

The CAS Registry Mumber 1613320-24-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,1,3,3,2 and 0 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1613320-24:
(9*1)+(8*6)+(7*1)+(6*3)+(5*3)+(4*2)+(3*0)+(2*2)+(1*4)=113
113 % 10 = 3
So 1613320-24-3 is a valid CAS Registry Number.

Bio-inspired synthesis of rare and unnatural carbohydrates and cyclitols through strain driven epimerization

Mohanrao, Raja,Asokan, Aromal,Sureshan, Kana M.

, p. 6707 - 6710 (2014)

We report a bio-inspired, strain driven epimerization of trans-ketals to cis-ketals through an enolate intermediate. Swern oxidation of a hydroxyl group adjacent to a trans-ketal effects both oxidation and its epimerization to cis-ketal. This novel and general strategy allows inversion of up to three contiguous stereocenters and has been illustrated by the synthesis of several unnatural/rare isomers of carbohydrates/cyclitols from their naturally abundant isomers. This journal is the Partner Organisations 2014.
