The CAS Registry Mumber 361-02-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,6 and 1 respectively; the second part has 2 digits, 0 and 2 respectively. Calculate Digit Verification of CAS Registry Number 361-02: (5*3)+(4*6)+(3*1)+(2*0)+(1*2)=44 44 % 10 = 4 So 361-02-4 is a valid CAS Registry Number.
