Check Digit Verification of cas no
The CAS Registry Mumber 89152-17-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,1,5 and 2 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 89152-17:
(7*8)+(6*9)+(5*1)+(4*5)+(3*2)+(2*1)+(1*7)=150
150 % 10 = 0
So 89152-17-0 is a valid CAS Registry Number.
