125931-55-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 125931-55-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,5,9,3 and 1 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 125931-55:
(8*1)+(7*2)+(6*5)+(5*9)+(4*3)+(3*1)+(2*5)+(1*5)=127
127 % 10 = 7
So 125931-55-7 is a valid CAS Registry Number.
