134643-07-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 134643-07-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,6,4 and 3 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 134643-07:
(8*1)+(7*3)+(6*4)+(5*6)+(4*4)+(3*3)+(2*0)+(1*7)=115
115 % 10 = 5
So 134643-07-5 is a valid CAS Registry Number.
