Check Digit Verification of cas no
The CAS Registry Mumber 20025-60-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,0,2 and 5 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 20025-60:
(7*2)+(6*0)+(5*0)+(4*2)+(3*5)+(2*6)+(1*0)=49
49 % 10 = 9
So 20025-60-9 is a valid CAS Registry Number.
