72409-45-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 72409-45-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,4,0 and 9 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 72409-45:
(7*7)+(6*2)+(5*4)+(4*0)+(3*9)+(2*4)+(1*5)=121
121 % 10 = 1
So 72409-45-1 is a valid CAS Registry Number.

Facile and highly selective 5′-desilylation of multisilylated nucleosides
Zhu, Xue-Feng,Williams, Howard J.,Ian Scott
, p. 2305 - 2306 (2000)
The facile and highly selective 5′-desilylation of multisilylated nucleosides was discussed. The selective 5′-desilylation using aqueous acetic acid can be improved if THF is added as a co-solvent. It was found that the use of THF increases the solubility
