Check Digit Verification of cas no
The CAS Registry Mumber 3209-71-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,2,0 and 9 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 3209-71:
(6*3)+(5*2)+(4*0)+(3*9)+(2*7)+(1*1)=70
70 % 10 = 0
So 3209-71-0 is a valid CAS Registry Number.
