Check Digit Verification of cas no
The CAS Registry Mumber 120285-30-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,2,8 and 5 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 120285-30:
(8*1)+(7*2)+(6*0)+(5*2)+(4*8)+(3*5)+(2*3)+(1*0)=85
85 % 10 = 5
So 120285-30-5 is a valid CAS Registry Number.
