The CAS Registry Mumber 201804-50-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,1,8,0 and 4 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 201804-50:
(8*2)+(7*0)+(6*1)+(5*8)+(4*0)+(3*4)+(2*5)+(1*0)=84
84 % 10 = 4
