Check Digit Verification of cas no
The CAS Registry Mumber 120113-89-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,1,1 and 3 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 120113-89:
(8*1)+(7*2)+(6*0)+(5*1)+(4*1)+(3*3)+(2*8)+(1*9)=65
65 % 10 = 5
So 120113-89-5 is a valid CAS Registry Number.
