Check Digit Verification of cas no
The CAS Registry Mumber 20069-03-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,0,6 and 9 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 20069-03:
(7*2)+(6*0)+(5*0)+(4*6)+(3*9)+(2*0)+(1*3)=68
68 % 10 = 8
So 20069-03-8 is a valid CAS Registry Number.
