75428-49-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 75428-49-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,4,2 and 8 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 75428-49:
(7*7)+(6*5)+(5*4)+(4*2)+(3*8)+(2*4)+(1*9)=148
148 % 10 = 8
So 75428-49-8 is a valid CAS Registry Number.
