Check Digit Verification of cas no
The CAS Registry Mumber 160857-56-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,0,8,5 and 7 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 160857-56:
(8*1)+(7*6)+(6*0)+(5*8)+(4*5)+(3*7)+(2*5)+(1*6)=147
147 % 10 = 7
So 160857-56-7 is a valid CAS Registry Number.

Synthesis and characterization of some novel substituted benzenesulphonamides of potential hypoglycemic activity
Hanna,Said,Waly
, p. 1029 - 1031 (2007/10/02)
Two series of substituted benzenesulphonamides (Va-e and VIa-e) have been synthesized from 4-methoxycarbonyl-1-[p-(acetylamino)benzenesulphonylimino]pyridinium ylide (II) with a view to investigate their pharmacological activity. The structure of the synt
