Check Digit Verification of cas no

The CAS Registry Mumber 204583-33-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,4,5,8 and 3 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 204583-33:
(8*2)+(7*0)+(6*4)+(5*5)+(4*8)+(3*3)+(2*3)+(1*3)=115
115 % 10 = 5
So 204583-33-5 is a valid CAS Registry Number.

, (2008/06/13)

An optically active azole compound of the formula (I): STR1 wherein R1 and R2 are independently a hydrogen atom, a halogen atom, a haloalkyl group, a haloalkoxy group or an optionally substituted nitrogen-containing heterocyclic group; R3 is a hydrogen atom or an acyl group; Q is CH or N; --NA is a nitrogen-containing aromatic five-membered heterocyclic group having at least two adjacent nitrogen atoms as the ring-constituting atoms which may be substituted, or an aromatic condensed heterocyclic group having two or more nitrogen atoms as the ring-constituting atoms which may be substituted; and (R) shows that the carbon atom marked with (R) has R-configuration; provided that either of R1 and R2 is an optionally substituted nitrogen-containing heterocyclic group when --NA is an 1H-1,2,4-triazol-1-yl group, or a salt thereof, which is useful as an antifungal agent.
