128307-91-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128307-91-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,3,0 and 7 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 128307-91:
(8*1)+(7*2)+(6*8)+(5*3)+(4*0)+(3*7)+(2*9)+(1*1)=125
125 % 10 = 5
So 128307-91-5 is a valid CAS Registry Number.
