The CAS Registry Mumber 692-58-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,9 and 2 respectively; the second part has 2 digits, 5 and 8 respectively. Calculate Digit Verification of CAS Registry Number 692-58: (5*6)+(4*9)+(3*2)+(2*5)+(1*8)=90 90 % 10 = 0 So 692-58-0 is a valid CAS Registry Number.
