344569-52-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 344569-52-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,4,5,6 and 9 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 344569-52:
(8*3)+(7*4)+(6*4)+(5*5)+(4*6)+(3*9)+(2*5)+(1*2)=164
164 % 10 = 4
So 344569-52-4 is a valid CAS Registry Number.

A diastereocontrolled route to the tetrahydropyran nucleus of pseudomonic acids
Taniguchi, Takahiko,Ogasawara, Kunio
, p. 3359 - 3361 (2007/10/03)
A diastereocontrolled synthesis of the tetrahydropyran nucleus of pseudomonic acids has been achieved starting from a chiral building block, which we have developed. The key step is a convex-face reduction of the block having a biased framework which allo
