125989-48-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 125989-48-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,5,9,8 and 9 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 125989-48:
(8*1)+(7*2)+(6*5)+(5*9)+(4*8)+(3*9)+(2*4)+(1*8)=172
172 % 10 = 2
So 125989-48-2 is a valid CAS Registry Number.
