The CAS Registry Mumber 6235-10-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,2,3 and 5 respectively; the second part has 2 digits, 1 and 0 respectively. Calculate Digit Verification of CAS Registry Number 6235-10: (6*6)+(5*2)+(4*3)+(3*5)+(2*1)+(1*0)=75 75 % 10 = 5 So 6235-10-5 is a valid CAS Registry Number.
