Check Digit Verification of cas no
The CAS Registry Mumber 198903-01-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,8,9,0 and 3 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 198903-01:
(8*1)+(7*9)+(6*8)+(5*9)+(4*0)+(3*3)+(2*0)+(1*1)=174
174 % 10 = 4
So 198903-01-4 is a valid CAS Registry Number.
