Check Digit Verification of cas no
The CAS Registry Mumber 20091-45-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,0,9 and 1 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 20091-45:
(7*2)+(6*0)+(5*0)+(4*9)+(3*1)+(2*4)+(1*5)=66
66 % 10 = 6
So 20091-45-6 is a valid CAS Registry Number.
