134415-28-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 134415-28-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,4,1 and 5 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 134415-28:
(8*1)+(7*3)+(6*4)+(5*4)+(4*1)+(3*5)+(2*2)+(1*8)=104
104 % 10 = 4
So 134415-28-4 is a valid CAS Registry Number.
