Check Digit Verification of cas no
The CAS Registry Mumber 89410-09-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,4,1 and 0 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 89410-09:
(7*8)+(6*9)+(5*4)+(4*1)+(3*0)+(2*0)+(1*9)=143
143 % 10 = 3
So 89410-09-3 is a valid CAS Registry Number.
