The CAS Registry Mumber 155304-02-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,5,3,0 and 4 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 155304-02:
(8*1)+(7*5)+(6*5)+(5*3)+(4*0)+(3*4)+(2*0)+(1*2)=102
102 % 10 = 2
