Check Digit Verification of cas no
The CAS Registry Mumber 528560-94-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,2,8,5,6 and 0 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 528560-94:
(8*5)+(7*2)+(6*8)+(5*5)+(4*6)+(3*0)+(2*9)+(1*4)=173
173 % 10 = 3
So 528560-94-3 is a valid CAS Registry Number.
