125116-34-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 125116-34-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,5,1,1 and 6 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 125116-34:
(8*1)+(7*2)+(6*5)+(5*1)+(4*1)+(3*6)+(2*3)+(1*4)=89
89 % 10 = 9
So 125116-34-9 is a valid CAS Registry Number.
