Check Digit Verification of cas no
The CAS Registry Mumber 6459-70-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,5 and 9 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 6459-70:
(6*6)+(5*4)+(4*5)+(3*9)+(2*7)+(1*0)=117
117 % 10 = 7
So 6459-70-7 is a valid CAS Registry Number.
