Check Digit Verification of cas no
The CAS Registry Mumber 159831-28-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,9,8,3 and 1 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 159831-28:
(8*1)+(7*5)+(6*9)+(5*8)+(4*3)+(3*1)+(2*2)+(1*8)=164
164 % 10 = 4
So 159831-28-4 is a valid CAS Registry Number.
