195503-34-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 195503-34-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,5,5,0 and 3 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 195503-34:
(8*1)+(7*9)+(6*5)+(5*5)+(4*0)+(3*3)+(2*3)+(1*4)=145
145 % 10 = 5
So 195503-34-5 is a valid CAS Registry Number.
