Check Digit Verification of cas no
The CAS Registry Mumber 129054-01-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,0,5 and 4 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 129054-01:
(8*1)+(7*2)+(6*9)+(5*0)+(4*5)+(3*4)+(2*0)+(1*1)=109
109 % 10 = 9
So 129054-01-9 is a valid CAS Registry Number.
