Check Digit Verification of cas no
The CAS Registry Mumber 5421-70-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,4,2 and 1 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 5421-70:
(6*5)+(5*4)+(4*2)+(3*1)+(2*7)+(1*0)=75
75 % 10 = 5
So 5421-70-5 is a valid CAS Registry Number.
