Check Digit Verification of cas no
The CAS Registry Mumber 134856-03-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,8,5 and 6 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 134856-03:
(8*1)+(7*3)+(6*4)+(5*8)+(4*5)+(3*6)+(2*0)+(1*3)=134
134 % 10 = 4
So 134856-03-4 is a valid CAS Registry Number.

Hair dyeing composition containing an aryldiamine and a substituted catechol
-
, (2008/06/13)
A composition for use in the dyeing of keratinous fibre such as hair includes an aqueous anaerobic solution of an aryldiamine and a substituted catechol. Optionally, an aromatic coupling agent can also be incorporated in the composition to modify the shade of color produced. Anaerobic storage conditions can, for example, be maintained by packing the composition in an aerosol container with a halocarbon propellant.
