The CAS Registry Mumber 78186-10-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,1,8 and 6 respectively; the second part has 2 digits, 1 and 0 respectively. Calculate Digit Verification of CAS Registry Number 78186-10: (7*7)+(6*8)+(5*1)+(4*8)+(3*6)+(2*1)+(1*0)=154 154 % 10 = 4 So 78186-10-4 is a valid CAS Registry Number.
