Check Digit Verification of cas no
The CAS Registry Mumber 20317-19-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,3,1 and 7 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 20317-19:
(7*2)+(6*0)+(5*3)+(4*1)+(3*7)+(2*1)+(1*9)=65
65 % 10 = 5
So 20317-19-5 is a valid CAS Registry Number.
