Check Digit Verification of cas no

The CAS Registry Mumber 1259874-80-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,9,8,7 and 4 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1259874-80:
(9*1)+(8*2)+(7*5)+(6*9)+(5*8)+(4*7)+(3*4)+(2*8)+(1*0)=210
210 % 10 = 0
So 1259874-80-0 is a valid CAS Registry Number.

Design and synthesis of α-carboxy phosphononucleosides

Debarge, Sebastien,Balzarini, Jan,Maguire, Anita R.

, p. 105 - 126 (2011/04/17)

Rhodium catalyzed O-H insertion reactions employing α- diazophosphonate 20 with appropriately protected thymidine, uridine, cytosine, adenosine and guanosine derivatives leads to novel 5′-phosphononucleoside derivatives. Deprotection led to a novel series of phosphono derivatives bearing a carboxylic acid moiety adjacent to the phosphonate group with potential antiviral and/or anticancer activity. The phosphononucleosides bearing an α-carboxylic acid group are envisaged as potential diphosphate mimics. Conversion to mono- and diphosphorylated phosphononucleosides has been effected for evaluation as nucleoside triphosphate mimics. Most of the novel phosphononucleosides proved to be inactive against a variety of DNA and RNA viruses. Only the phosphono AZT derivatives 56-59 showed weak activity against HIV-1 and HIV-2.
