134961-76-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 134961-76-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,9,6 and 1 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 134961-76:
(8*1)+(7*3)+(6*4)+(5*9)+(4*6)+(3*1)+(2*7)+(1*6)=145
145 % 10 = 5
So 134961-76-5 is a valid CAS Registry Number.
