131513-76-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 131513-76-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,5,1 and 3 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 131513-76:
(8*1)+(7*3)+(6*1)+(5*5)+(4*1)+(3*3)+(2*7)+(1*6)=93
93 % 10 = 3
So 131513-76-3 is a valid CAS Registry Number.

Reductive Lithiation Mediated Anionic Cyclizations and -Sigmatropic Rearrangements
Broka, Chris A.,Shen, Tong
, p. 2981 - 2984 (2007/10/02)
The anionic cyclization of several α-alkoxylithiums derived by transmetalation from their corresponding (tributylstannyl)methyl ethers is described.The resulting 2,4-disubstituted tetrahydrofurans are primarily the cis stereoisomers.It is also shown that
