The CAS Registry Mumber 129780-81-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,7,8 and 0 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 129780-81:
(8*1)+(7*2)+(6*9)+(5*7)+(4*8)+(3*0)+(2*8)+(1*1)=160
160 % 10 = 0
So 129780-81-0 is a valid CAS Registry Number.
