Check Digit Verification of cas no
The CAS Registry Mumber 120834-04-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,8,3 and 4 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 120834-04:
(8*1)+(7*2)+(6*0)+(5*8)+(4*3)+(3*4)+(2*0)+(1*4)=90
90 % 10 = 0
So 120834-04-0 is a valid CAS Registry Number.
