Check Digit Verification of cas no
The CAS Registry Mumber 20893-64-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,8,9 and 3 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 20893-64:
(7*2)+(6*0)+(5*8)+(4*9)+(3*3)+(2*6)+(1*4)=115
115 % 10 = 5
So 20893-64-5 is a valid CAS Registry Number.
