132971-62-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 132971-62-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,9,7 and 1 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 132971-62:
(8*1)+(7*3)+(6*2)+(5*9)+(4*7)+(3*1)+(2*6)+(1*2)=131
131 % 10 = 1
So 132971-62-1 is a valid CAS Registry Number.

Total synthesis of xerulinic acid
Sorg, Achim,Brueckner, Reinhard
, p. 4523 - 4526 (2004)
An inhibitor of the biosynthesis of cholesterol, xerulinic acid, has been synthesized for the first time. The convergent approach applied involves the palladium-catalyzed coupling of an enediynoic ester building block, a conjunctive C6 bisstannane, and a bromine-containing methylenebutenolide (see scheme; R = Me3SiCH2CH 2).
