The CAS Registry Mumber 805-38-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,0 and 5 respectively; the second part has 2 digits, 3 and 8 respectively. Calculate Digit Verification of CAS Registry Number 805-38: (5*8)+(4*0)+(3*5)+(2*3)+(1*8)=69 69 % 10 = 9 So 805-38-9 is a valid CAS Registry Number.
