Check Digit Verification of cas no
The CAS Registry Mumber 152189-89-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,2,1,8 and 9 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 152189-89:
(8*1)+(7*5)+(6*2)+(5*1)+(4*8)+(3*9)+(2*8)+(1*9)=144
144 % 10 = 4
So 152189-89-4 is a valid CAS Registry Number.
