134143-47-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 134143-47-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,1,4 and 3 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 134143-47:
(8*1)+(7*3)+(6*4)+(5*1)+(4*4)+(3*3)+(2*4)+(1*7)=98
98 % 10 = 8
So 134143-47-8 is a valid CAS Registry Number.
