917081-91-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 917081-91-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,7,0,8 and 1 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 917081-91:
(8*9)+(7*1)+(6*7)+(5*0)+(4*8)+(3*1)+(2*9)+(1*1)=175
175 % 10 = 5
So 917081-91-5 is a valid CAS Registry Number.

Synthesis of Rigid Rod, Trigonal, and Tetrahedral Nucleobase-Terminated Molecules

Jin, Xiao-Yang,Wu, Chuan-Shuo,Liu, An-Di,Liu, Li,Cheng, Liang

, p. 1643 - 1651 (2022/01/12)

An efficient fragment splicing method for the construction of multiple nucleobase-terminated monomers has been developed. Conformationally fixed rod, trigonal planar and tetrahedral thymine and adenine structures were generated in moderate to good yields,

Efficient N-arylation and N-alkenylation of the five DNA/RNA nucleobases

Jacobsen, Mikkel F.,Knudsen, Martin M.,Gothelf, Kurt V.

, p. 9183 - 9190 (2007/10/03)

(Chemical Equation Presented) A general approach to N-arylation and N-alkenylation of all five DNA/RNA nucleobases at the nitrogen atom normally attached to the sugar moiety in DNA or RNA has been developed. Various protected or masked nucleobases engaged
