1295509-53-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1295509-53-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,9,5,5,0 and 9 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1295509-53:
(9*1)+(8*2)+(7*9)+(6*5)+(5*5)+(4*0)+(3*9)+(2*5)+(1*3)=183
183 % 10 = 3
So 1295509-53-3 is a valid CAS Registry Number.
