Check Digit Verification of cas no
The CAS Registry Mumber 886999-34-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,6,9,9 and 9 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 886999-34:
(8*8)+(7*8)+(6*6)+(5*9)+(4*9)+(3*9)+(2*3)+(1*4)=274
274 % 10 = 4
So 886999-34-4 is a valid CAS Registry Number.
