Check Digit Verification of cas no
The CAS Registry Mumber 130-19-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,3 and 0 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 130-19:
(5*1)+(4*3)+(3*0)+(2*1)+(1*9)=28
28 % 10 = 8
So 130-19-8 is a valid CAS Registry Number.
