65109-11-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 65109-11-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,1,0 and 9 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 65109-11:
(7*6)+(6*5)+(5*1)+(4*0)+(3*9)+(2*1)+(1*1)=107
107 % 10 = 7
So 65109-11-7 is a valid CAS Registry Number.

ISOMERIZATION OF tert-BUTYLDIMETHYLSILYL PROTECTING GROUPS IN RIBONUCLEOSIDES
Ogilvie, Kelvin K.,Entwistle, Douglas W.
, p. 203 - 210 (2007/10/02)
The tert-butyldimethylsilyl group undergoes isomerization between O-2' and O-3' in ribonucleosides in solution.Isomerization is most rapid in protic solvents and extremely slow in such solvents as dry dimethyl sulfoxide, pyridine, oxolane, chloroform, or
