Check Digit Verification of cas no
The CAS Registry Mumber 28569-48-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,5,6 and 9 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 28569-48:
(7*2)+(6*8)+(5*5)+(4*6)+(3*9)+(2*4)+(1*8)=154
154 % 10 = 4
So 28569-48-4 is a valid CAS Registry Number.
