1053267-56-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1053267-56-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,5,3,2,6 and 7 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1053267-56:
(9*1)+(8*0)+(7*5)+(6*3)+(5*2)+(4*6)+(3*7)+(2*5)+(1*6)=133
133 % 10 = 3
So 1053267-56-3 is a valid CAS Registry Number.

Automated RNA-synthesis with photocleavable sugar and nucleobase protecting groups
Stutz, Alfred,Pitsch, Stefan
, p. 930 - 934 (2007/10/03)
A new synthetic method for the N-alkyloxycarbonylation of adenine and guanine nucleosides was developed and used for the preparation of RNA- phosphoramidites carrying photolabile sugar and nucleobase protecting groups. From these building blocks, a heptam
