Check Digit Verification of cas no
The CAS Registry Mumber 117-61-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,1 and 7 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 117-61:
(5*1)+(4*1)+(3*7)+(2*6)+(1*1)=43
43 % 10 = 3
So 117-61-3 is a valid CAS Registry Number.

A new class of cellulose reactive dyes have a sulphonated benzene, naphthalene or naphthalene azobenzene diazo component coupled on to a class of coupling components of the formula: SPC1 In which T1 is H, monocyclic aryl, OH, CO2 H, aminocarbonyl, lower alkyl, lower alkoxy and lower alkoxycarbonyl, T2 is H, CO2 H, lower alkyl, lower alkoxy, monocyclic aryl, benzyl, aminocarbonyl and lower alkoxycarbonyl, the diazo component carrying a cellulose-reactive group. Also included are dyes in which two moles of such a monoazo dye are linked through a diamine radical. Cr and Co complexes of dyes in which the diazo component is a o-aminophenol or o-aminonaphthol are included. These dyes are usefully employed to color cellulose, wool or polyamide textile materials. These dyes impart to the textile materials deep shades having excellent fastness to light and to the wet treatments which are commonly applied to cellulose textile materials.
