Check Digit Verification of cas no
The CAS Registry Mumber 20006-88-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,0,0 and 6 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 20006-88:
(7*2)+(6*0)+(5*0)+(4*0)+(3*6)+(2*8)+(1*8)=56
56 % 10 = 6
