843639-16-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 843639-16-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,3,6,3 and 9 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 843639-16:
(8*8)+(7*4)+(6*3)+(5*6)+(4*3)+(3*9)+(2*1)+(1*6)=187
187 % 10 = 7
So 843639-16-7 is a valid CAS Registry Number.

Size-expanded analogues of dG and dC: Synthesis and pairing properties in DNA
Liu, Haibo,Gao, Jianmin,Kool, Eric T.
, p. 639 - 647 (2007/10/03)
(Chemical Equation Presented) We describe the completion of the set of four benzo-fused expanded DNA (xDNA) nucleoside analogues. We previously reported the development of benzo-fused analogues of dA and dT and their inclusion in an exceptionally stable n
