The CAS Registry Mumber 6156-02-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,1,5 and 6 respectively; the second part has 2 digits, 0 and 2 respectively. Calculate Digit Verification of CAS Registry Number 6156-02: (6*6)+(5*1)+(4*5)+(3*6)+(2*0)+(1*2)=81 81 % 10 = 1 So 6156-02-1 is a valid CAS Registry Number.
