125923-13-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 125923-13-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,5,9,2 and 3 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 125923-13:
(8*1)+(7*2)+(6*5)+(5*9)+(4*2)+(3*3)+(2*1)+(1*3)=119
119 % 10 = 9
So 125923-13-9 is a valid CAS Registry Number.
