Check Digit Verification of cas no
The CAS Registry Mumber 197070-03-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,7,0,7 and 0 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 197070-03:
(8*1)+(7*9)+(6*7)+(5*0)+(4*7)+(3*0)+(2*0)+(1*3)=144
144 % 10 = 4
So 197070-03-4 is a valid CAS Registry Number.
