231957-29-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 231957-29-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,3,1,9,5 and 7 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 231957-29:
(8*2)+(7*3)+(6*1)+(5*9)+(4*5)+(3*7)+(2*2)+(1*9)=142
142 % 10 = 2
So 231957-29-2 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
