129509-31-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129509-31-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,5,0 and 9 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 129509-31:
(8*1)+(7*2)+(6*9)+(5*5)+(4*0)+(3*9)+(2*3)+(1*1)=135
135 % 10 = 5
So 129509-31-5 is a valid CAS Registry Number.
