Check Digit Verification of cas no
The CAS Registry Mumber 119258-93-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,2,5 and 8 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 119258-93:
(8*1)+(7*1)+(6*9)+(5*2)+(4*5)+(3*8)+(2*9)+(1*3)=144
144 % 10 = 4
So 119258-93-4 is a valid CAS Registry Number.
