The CAS Registry Mumber 353-04-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,5 and 3 respectively; the second part has 2 digits, 0 and 4 respectively. Calculate Digit Verification of CAS Registry Number 353-04: (5*3)+(4*5)+(3*3)+(2*0)+(1*4)=48 48 % 10 = 8 So 353-04-8 is a valid CAS Registry Number.
