218152-30-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 218152-30-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,8,1,5 and 2 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 218152-30:
(8*2)+(7*1)+(6*8)+(5*1)+(4*5)+(3*2)+(2*3)+(1*0)=108
108 % 10 = 8
So 218152-30-8 is a valid CAS Registry Number.

N2-acetyl-O6-(2-(p-nitrophenyl)ethyl)guanine: A convenient building block for the synthesis of 9-substituted guanine derivatives

Zhou, Jinglan,Tsai, Jui-Yi,Bouhadir, Kamal,Shevlin, Philip B.

, p. 3003 - 3009 (1999)

Readily accessible N2-acetyl-O6-(2-(p-nitrophenyl)ethyl)guanine can undergo Mitsunobu reactions with either a primary or secondary alcohol to generate guanine derivatives. X-ray data indicates that only the desired 9- subsituted derivatives of guanine are formed.

Synthesis of N-Boc and N-Fmoc dipeptoids with nucleobase residues as peptoid nucleic acid monomers

Wu, Yun,Xu, Jie-Cheng,Liu, Jing,Jin, You-Xing

, p. 3373 - 3381 (2007/10/03)

The synthesis of Boc and Fmoc protected peptoid nucleic acid monomers bearing thymine (4a, 4b), adenine (6a, 6b) or guanine (7a, 7b) on the side chain is described. These nucleobases were attached to the amino group of glycine via an ethylene linkage using the Mitsunobu reaction, except cytosine, which was attached using alkylation. After deprotection, these amino acids have been used for synthesizing N-Boc and N-Fmoc dipeptoids.
