Check Digit Verification of cas no
The CAS Registry Mumber 70259-86-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,2,5 and 9 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 70259-86:
(7*7)+(6*0)+(5*2)+(4*5)+(3*9)+(2*8)+(1*6)=128
128 % 10 = 8
So 70259-86-8 is a valid CAS Registry Number.
