The CAS Registry Mumber 4821-35-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,8,2 and 1 respectively; the second part has 2 digits, 3 and 5 respectively. Calculate Digit Verification of CAS Registry Number 4821-35: (6*4)+(5*8)+(4*2)+(3*1)+(2*3)+(1*5)=86 86 % 10 = 6 So 4821-35-6 is a valid CAS Registry Number.
