144733-76-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 144733-76-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,7,3 and 3 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 144733-76:
(8*1)+(7*4)+(6*4)+(5*7)+(4*3)+(3*3)+(2*7)+(1*6)=136
136 % 10 = 6
So 144733-76-6 is a valid CAS Registry Number.

A new synthetic route to chiral, multiply functionalized cyclopentane rings
Contelles,Ruiz,Sanchez,Jimeno
, p. 5261 - 5264 (2007/10/02)
The tribyltin hydride mediated free radical cyclization of sugar derivatives 4-6 gives the annulated furanose 9-11 in good yield and high diastereoselectivity. This protocol is a new synthetic route for the preparation of complex cyclopentanoid molecules.
