913531-39-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 913531-39-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,3,5,3 and 1 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 913531-39:
(8*9)+(7*1)+(6*3)+(5*5)+(4*3)+(3*1)+(2*3)+(1*9)=152
152 % 10 = 2
So 913531-39-2 is a valid CAS Registry Number.

Regioselective synthesis of pyrone-annulated sulfur heterocycles by aryl radical cyclization
Majumdar,Muhuri
, p. 2725 - 2730 (2008/02/05)
The tri-n-butyltin hydride mediated cyclization of a number of 4-(2′-bromophenoxymethyl)-7-methylthiopyrano[3,2-c]pyran-5-ones have been carried out to afford tetracyclic [6,6]pyranothiopyrans in 70-80% yield and good to excellent diastereoselectivity. Th
