Check Digit Verification of cas no

The CAS Registry Mumber 331845-74-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,1,8,4 and 5 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 331845-74:
(8*3)+(7*3)+(6*1)+(5*8)+(4*4)+(3*5)+(2*7)+(1*4)=140
140 % 10 = 0
So 331845-74-0 is a valid CAS Registry Number.

Design, synthesis and antimalarial activity of benzene and isoquinoline sulfonamide derivatives

Kumar Parai, Maloy,Panda, Gautam,Srivastava, Kumkum,Kumar Puri, Sunil

, p. 776 - 781 (2008/09/18)

A new series of benzene and isoquinoline sulfonamide derivatives were synthesized by nucleophilic displacement reaction on benzene and isoquinoline sulfonyl chlorides by substituted amines (primary and secondary). The title compounds were evaluated for an

THIENOPYRAZOLE DERIVATIVE HAVING PDE7 INHIBITORY ACTIVITY

-

Page/Page column 25, (2008/06/13)

To provide thienopyrazole derivatives inhibiting PDE 7 selectively, and therefore, enhance cellular cAMP level. Consequently, the compound is useful for treating various kinds of disease such as allergic diseases, inflammatory diseases or immunologic diseases. The compound is thienopyrazole compound represented by the following formula (I): [wherein, especially, R 1 is a cyclohexyl, a cycloheptyl group or a tetrahydropyranyl group; R 2 is methyl; R 3 is a hydrogen atom; and R 4 is a group: -CONR 5 R 6 (in which any one of R 5 and R 6 is a hydrogen atom)].
