Check Digit Verification of cas no

The CAS Registry Mumber 183387-07-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,3,3,8 and 7 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 183387-07:
(8*1)+(7*8)+(6*3)+(5*3)+(4*8)+(3*7)+(2*0)+(1*7)=157
157 % 10 = 7
So 183387-07-7 is a valid CAS Registry Number.

-

, (2008/06/13)

Disclosed is a process for preparing novel trans-3-alkyloxy-4-hydroxytetrahydrofurans including racemic and substantially enantiomerically pure (3S,4S)-trans-3-alk(en)yloxy-4-hydroxytetrahydrofurans and (3R,4R)-trans-3-alk(en)yloxy-4-acyloxytetrahydrofura

Enzymic Preparation of Tetrahydrofuran Derivatives of High Optical Purity

Seemayer, Robert,Schneider, Manfred P.

, p. 2359 - 2360 (2007/10/02)

3,4-Disubstituted tetrahydrofurans (1)-(4) and (7) of high optical purities have been prepared by enantioselective enzyme hydrolysis of their acetates (+/-)-(1a) - (4a) and (7a) using a lipase from Pseudomonas sp. (SAM-II).
