Check Digit Verification of cas no

The CAS Registry Mumber 1259-22-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,2,5 and 9 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1259-22:
(6*1)+(5*2)+(4*5)+(3*9)+(2*2)+(1*2)=69
69 % 10 = 9
So 1259-22-9 is a valid CAS Registry Number.

The regioselective Cu(I)-catalyzed 1,3-dipolar cycloaddition of 17α- and 17β-azidoandrost-5-en-3β-ol epimers (3b and 5b) with different terminal alkynes afforded novel 1,4-substituted triazolyl derivatives (8a–k and 9a–k). For the preparation of 5′-iodo-1

PREPARATION OF UNLABELLED AND 3H>-LABELLED EPITESTOSTERONE AND ITS METABOLITES

Kasal, Alexander,Fuksova, Kveta,Pouzar, Vladimir

, p. 600 - 611 (2007/10/02)

Cold as well as 3H>-labelled substrates and metabolites IX-XI, XV, XVI, XX-XXII, XXIV, XXV and XXVIII were prepared by catalytic hydrogenation of epitestosterone (VIII) and Λ1-dehydroepitestosterone (XIII).The key step in the preparation of compound XXVIII was reaction of 3β-tosylates XXVI and XXX with potassium nitrite in dimethyl sulfoxide.
