Check Digit Verification of cas no
The CAS Registry Mumber 120021-39-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,0,2 and 1 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 120021-39:
(8*1)+(7*2)+(6*0)+(5*0)+(4*2)+(3*1)+(2*3)+(1*9)=48
48 % 10 = 8
So 120021-39-8 is a valid CAS Registry Number.
