The CAS Registry Mumber 855-12-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,5 and 5 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 855-12:
(5*8)+(4*5)+(3*5)+(2*1)+(1*2)=79
79 % 10 = 9
So 855-12-9 is a valid CAS Registry Number.
