The CAS Registry Mumber 856675-74-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,6,6,7 and 5 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 856675-74:
(8*8)+(7*5)+(6*6)+(5*6)+(4*7)+(3*5)+(2*7)+(1*4)=226
226 % 10 = 6
So 856675-74-6 is a valid CAS Registry Number.
