117903-25-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 117903-25-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,9,0 and 3 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 117903-25:
(8*1)+(7*1)+(6*7)+(5*9)+(4*0)+(3*3)+(2*2)+(1*5)=120
120 % 10 = 0
So 117903-25-0 is a valid CAS Registry Number.
