189281-61-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 189281-61-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,2,8 and 1 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 189281-61:
(8*1)+(7*8)+(6*9)+(5*2)+(4*8)+(3*1)+(2*6)+(1*1)=176
176 % 10 = 6
So 189281-61-6 is a valid CAS Registry Number.

Direct SNAr amination of fluorinated imidazo[4,5-c]pyridine nucleosides: Efficient syntheses of 3-fluoro-3-deazaadenosine analogs

Sakthivel, Kandasamy,Cook, P. Dan

, p. 3883 - 3887 (2007/10/03)

This paper describes the ready preparation of 3,6-difluoro-3-deazapurine (4,7-difluoroimidazo[4,5-c]pyridine). This novel base was glycosylated under mild conditions using three different ribose sugar analogs. 3,6-Difluoro-3- deazapurine ribonucleoside an
