134860-28-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 134860-28-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,8,6 and 0 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 134860-28:
(8*1)+(7*3)+(6*4)+(5*8)+(4*6)+(3*0)+(2*2)+(1*8)=129
129 % 10 = 9
So 134860-28-9 is a valid CAS Registry Number.
