129309-03-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129309-03-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,3,0 and 9 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 129309-03:
(8*1)+(7*2)+(6*9)+(5*3)+(4*0)+(3*9)+(2*0)+(1*3)=121
121 % 10 = 1
So 129309-03-1 is a valid CAS Registry Number.
