Check Digit Verification of cas no
The CAS Registry Mumber 89047-53-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,0,4 and 7 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 89047-53:
(7*8)+(6*9)+(5*0)+(4*4)+(3*7)+(2*5)+(1*3)=160
160 % 10 = 0
So 89047-53-0 is a valid CAS Registry Number.
