Check Digit Verification of cas no
The CAS Registry Mumber 875-61-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,7 and 5 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 875-61:
(5*8)+(4*7)+(3*5)+(2*6)+(1*1)=96
96 % 10 = 6
So 875-61-6 is a valid CAS Registry Number.
