Check Digit Verification of cas no
The CAS Registry Mumber 89642-49-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,6,4 and 2 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 89642-49:
(7*8)+(6*9)+(5*6)+(4*4)+(3*2)+(2*4)+(1*9)=179
179 % 10 = 9
So 89642-49-9 is a valid CAS Registry Number.
