The CAS Registry Mumber 52042-58-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,0,4 and 2 respectively; the second part has 2 digits, 5 and 8 respectively. Calculate Digit Verification of CAS Registry Number 52042-58: (7*5)+(6*2)+(5*0)+(4*4)+(3*2)+(2*5)+(1*8)=87 87 % 10 = 7 So 52042-58-7 is a valid CAS Registry Number.
