134513-65-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 134513-65-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,5,1 and 3 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 134513-65:
(8*1)+(7*3)+(6*4)+(5*5)+(4*1)+(3*3)+(2*6)+(1*5)=108
108 % 10 = 8
So 134513-65-8 is a valid CAS Registry Number.
