Check Digit Verification of cas no
The CAS Registry Mumber 169220-56-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,9,2,2 and 0 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 169220-56:
(8*1)+(7*6)+(6*9)+(5*2)+(4*2)+(3*0)+(2*5)+(1*6)=138
138 % 10 = 8
So 169220-56-8 is a valid CAS Registry Number.
