134919-56-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 134919-56-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,9,1 and 9 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 134919-56:
(8*1)+(7*3)+(6*4)+(5*9)+(4*1)+(3*9)+(2*5)+(1*6)=145
145 % 10 = 5
So 134919-56-5 is a valid CAS Registry Number.
