3-4Check Digit Verification of cas no
The CAS Registry Mumber 75030-18-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,0,3 and 0 respectively; the second part has 2 digits, 1 and 8 respectively.Calculate Digit Verification of CAS Registry Number 75030-18:
(7*7)+(6*5)+(5*0)+(4*3)+(3*0)+(2*1)+(1*8)=101
101 % 10 = 1
So 75030-18-1 is a valid CAS Registry Number.
