134340-50-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 134340-50-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,3,4 and 0 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 134340-50:
(8*1)+(7*3)+(6*4)+(5*3)+(4*4)+(3*0)+(2*5)+(1*0)=94
94 % 10 = 4
So 134340-50-4 is a valid CAS Registry Number.
