144677-72-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 144677-72-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,6,7 and 7 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 144677-72:
(8*1)+(7*4)+(6*4)+(5*6)+(4*7)+(3*7)+(2*7)+(1*2)=155
155 % 10 = 5
So 144677-72-5 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.
