149622-84-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 149622-84-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,9,6,2 and 2 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 149622-84:
(8*1)+(7*4)+(6*9)+(5*6)+(4*2)+(3*2)+(2*8)+(1*4)=154
154 % 10 = 4
So 149622-84-4 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
