Check Digit Verification of cas no

The CAS Registry Mumber 1042421-51-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,2,4,2 and 1 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1042421-51:
(9*1)+(8*0)+(7*4)+(6*2)+(5*4)+(4*2)+(3*1)+(2*5)+(1*1)=91
91 % 10 = 1
So 1042421-51-1 is a valid CAS Registry Number.

Novel bis-(arylsulfonamide) hydroxamate-based selective MMP inhibitors

Subramaniam, Rajesh,Haldar, Manas K.,Tobwala, Shakila,Ganguly, Bratati,Srivastava,Mallik, Sanku

supporting information; experimental part, p. 3333 - 3337 (2009/04/11)

A series of bis-(arylsulfonamide) hydroxamate inhibitors were synthesized. These compounds exhibit good potency against MMP-7 and MMP-9 depending on the nature, steric bulk, and substitution pattern of the substituents in the benzene ring. In general, the preliminary structure-activity relationships (SAR) suggest that among the DAPA hydroxamates (i) electron-rich benzene rings of the sulfonamides may produce better inhibitors than electron-poor analogs. However, potential H-bond acceptors can reverse the trend depending on the isozyme; (ii) isozyme selectivity between MMP-7 and -9 can be conferred through steric bulk and substitution pattern of the substituents in the benzene ring, and (iii) the MMP-10 inhibition pattern of the compounds paralleled that for MMP-9.
