485815-81-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 485815-81-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,8,5,8,1 and 5 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 485815-81:
(8*4)+(7*8)+(6*5)+(5*8)+(4*1)+(3*5)+(2*8)+(1*1)=194
194 % 10 = 4
So 485815-81-4 is a valid CAS Registry Number.

Photochemistry on Soluble Polymer Supports: Synthesis of Nucleosides
Zhong, Jian-Hua,Fishman, Alex,Lee-Ruff, Edward
, p. 4415 - 4417 (2007/10/03)
(Matrix Presented) A new soluble polymer support synthesis of nucleosides is described. The photochemical ring expansion of cyclobutanones in the presence of poly(ethylene glycol) (PEG) results in polymer-supported ribosides. These photoadducts can be cle
