Check Digit Verification of cas no
The CAS Registry Mumber 258856-30-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,8,8,5 and 6 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 258856-30:
(8*2)+(7*5)+(6*8)+(5*8)+(4*5)+(3*6)+(2*3)+(1*0)=183
183 % 10 = 3
So 258856-30-3 is a valid CAS Registry Number.
