The CAS Registry Mumber 129943-00-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,9,4 and 3 respectively; the second part has 2 digits, 0 and 0 respectively. Calculate Digit Verification of CAS Registry Number 129943-00: (8*1)+(7*2)+(6*9)+(5*9)+(4*4)+(3*3)+(2*0)+(1*0)=146 146 % 10 = 6 So 129943-00-6 is a valid CAS Registry Number.
