The CAS Registry Mumber 1899-76-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,9 and 9 respectively; the second part has 2 digits, 7 and 6 respectively. Calculate Digit Verification of CAS Registry Number 1899-76: (6*1)+(5*8)+(4*9)+(3*9)+(2*7)+(1*6)=129 129 % 10 = 9 So 1899-76-9 is a valid CAS Registry Number.
