Check Digit Verification of cas no
The CAS Registry Mumber 338420-60-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,8,4,2 and 0 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 338420-60:
(8*3)+(7*3)+(6*8)+(5*4)+(4*2)+(3*0)+(2*6)+(1*0)=133
133 % 10 = 3
So 338420-60-3 is a valid CAS Registry Number.
