Check Digit Verification of cas no
The CAS Registry Mumber 856120-28-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,6,1,2 and 0 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 856120-28:
(8*8)+(7*5)+(6*6)+(5*1)+(4*2)+(3*0)+(2*2)+(1*8)=160
160 % 10 = 0
So 856120-28-0 is a valid CAS Registry Number.
