The CAS Registry Mumber 1540-18-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,4 and 0 respectively; the second part has 2 digits, 1 and 8 respectively. Calculate Digit Verification of CAS Registry Number 1540-18: (6*1)+(5*5)+(4*4)+(3*0)+(2*1)+(1*8)=57 57 % 10 = 7 So 1540-18-7 is a valid CAS Registry Number.
