Check Digit Verification of cas no

The CAS Registry Mumber 13161-32-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,1,6 and 1 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 13161-32:
(7*1)+(6*3)+(5*1)+(4*6)+(3*1)+(2*3)+(1*2)=65
65 % 10 = 5
So 13161-32-5 is a valid CAS Registry Number.

A Biomimetic Synthesis of des -Hydroxy Paecilospirone

Feng, Zhen-Gao,Burnett, G. Leslie,Pettus, Thomas R. R.

supporting information, p. 1517 - 1519 (2018/05/16)

The carbon framework of des -hydroxy paecilospirone was rapidly synthesized using a biomimetic approach whereby an enol ether and an ortho -quinone methide (o- QM), each derived from the same lactone, were combined to arrive at the complete carbon skeleton of paecilospirone.

Regiocontrolled rearrangement of isobenzofurans

Egan, Ben A.,Paradowski, Michael,Thomas, Lynne H.,Marquez, Rodolfo

, p. 2086 - 2089 (2011/06/25)

Regioselective alkylation and oxidative rearrangement of isobenzofurans has been achieved to generate substituted 4,8- ihydroxyisochromanones in good yields and with complete regiocontrol.

Facile Interconversion of the Isomeric Acid Chlorides Derived from Half Methyl Esters of 3-Methoxyphthalic Acid

Gupta, Dahmendra N.,Hodge, Philip,Hurley, Peter N.

, p. 391 - 394 (2007/10/02)

The isomeric acid chlorides obtained by treating the half methyl esters of 3-methoxyphthalic acid with thionyl chloride interconvert so readily that it is not practical to isolate one acid chloride free of the other.At equilibrium the main isomer is the a
