6160-49-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6160-49-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,1,6 and 0 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 6160-49:
(6*6)+(5*1)+(4*6)+(3*0)+(2*4)+(1*9)=82
82 % 10 = 2
So 6160-49-2 is a valid CAS Registry Number.

Synthesis of novel Pyridine-, Pyrindine- and Isoquinoline-substituted α- and β-C-nucleosides of 2-deoxy-D-ribose

Seitz, Gunther,Lachmann, Jens

, p. 549 - 558 (2007/10/03)

The novel imido esters of 2-deoxy-α- and -β-D-ribose 8 and 9 have been synthesized and successfully transformed to the protected 1,2,4-triazine-C-nucleosides 11 and 12 using an inverse type Diels-Alder reaction with the 1,2,4,5-tetrazine 10. The electron deficient diazadiene system of both C-nucleosides 11 and 12 proved to be highly reactive in a consecutive [4 + 2] cycloaddition with inverse electron demand towards several electron rich dienophiles yielding after successful deprotection the novel pyridine-, pyrindine- and isoquinoline-C-nucleosides 15, 18 and 21 of 2-deoxy-α-D-ribose and 23, 25 and 27 of 2-deoxy-β-D-ribose.

STEREOCHEMICAL CONTROL AS A FUNCTION OF PROTECTING-GROUP PARTICIPATION IN 2-DEOXY-D-ERYTHRO-PENTOFURANOSYL NUCLEOSIDES

Wierenga, Wendell,Skulnick, Harvey I.

, p. 41 - 52 (2007/10/02)

Possible features controlling the anomeric ratios in the synthesis of the antiviral antibiotic dihydro-5-azathymidine have been examined.Replacement of the 3- and 5-(4-methylbenzoyl) protecting groups in 2-deoxy-D-erythro-pentofuranosyl chloride by benzyl
