318988-54-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 318988-54-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,1,8,9,8 and 8 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 318988-54:
(8*3)+(7*1)+(6*8)+(5*9)+(4*8)+(3*8)+(2*5)+(1*4)=194
194 % 10 = 4
So 318988-54-4 is a valid CAS Registry Number.
