Check Digit Verification of cas no

The CAS Registry Mumber 158327-96-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,8,3,2 and 7 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 158327-96:
(8*1)+(7*5)+(6*8)+(5*3)+(4*2)+(3*7)+(2*9)+(1*6)=159
159 % 10 = 9
So 158327-96-9 is a valid CAS Registry Number.

A concise synthesis of chiral 2-methyl chroman-4-ones: Stereo selective build-up of the chromanol moiety of anti-HIV agent, calanolide A

Rama Rao,Gaitonde,Prakash,Prahlada Rao

, p. 6347 - 6350 (2007/10/02)

Inter- and intramolecular Houben-Hoesch reactions have been used for the first time for the enantioselective synthesis of both the antipodes of 5,7-dimethoxy-2-methyl chroman-4-one. (E)-7-Methoxy-2-methyl chroman-4-one has been diastereoselectively elaborated to the dimethylchromanol moiety of calanolide A.
