Check Digit Verification of cas no

The CAS Registry Mumber 90086-91-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,0,8 and 6 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 90086-91:
(7*9)+(6*0)+(5*0)+(4*8)+(3*6)+(2*9)+(1*1)=132
132 % 10 = 2
So 90086-91-2 is a valid CAS Registry Number.

-

, (2008/06/13)

The invention relates to a process for dyeing keratinous fibres, comprising the simultaneous or sequential application of a component (A) containing at least one compound of formula (I): STR1 in which: R1 denotes hydrogen, alkyl, acetyl, benzoyl, phenyl or C1 -C4 carboxyalkyl, R2 and R3 denote hydrogen, alkyl, alkoxy, hydroxyalkyl, amino, halogen, nitro, alkylphenyl, phenyl, alkylamino or hydroxyalkylamino, and a component (B) containing at least (i) a compound of formula (II): STR2 in which: Y denotes OH or NR8 R9, R8 and R9, which are identical or different, denote hydrogen, aminoethyl, hydroxyethyl or C1 -C4 alkyl, R4 to R7 independently of each other denote a hydrogen atom, a C1 -C4 alkyl, a chlorine, a C1 -C4 alkoxy, an acetylamino, an aryloxy, not more than two of the groups R4 to R7 denote a hydrogen atom, excluding 2,5-dimethoxy-1,4-diaminobenzene, and the cosmetically acceptable salts, or (ii) a bisphenylalkylenediamine.
