Check Digit Verification of cas no
The CAS Registry Mumber 130203-30-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,2,0 and 3 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 130203-30:
(8*1)+(7*3)+(6*0)+(5*2)+(4*0)+(3*3)+(2*3)+(1*0)=54
54 % 10 = 4
So 130203-30-4 is a valid CAS Registry Number.
