129303-13-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129303-13-5 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 3 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 129303-13:
(8*1)+(7*2)+(6*9)+(5*3)+(4*0)+(3*3)+(2*1)+(1*3)=105
105 % 10 = 5
So 129303-13-5 is a valid CAS Registry Number.
