928148-80-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 928148-80-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,2,8,1,4 and 8 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 928148-80:
(8*9)+(7*2)+(6*8)+(5*1)+(4*4)+(3*8)+(2*8)+(1*0)=195
195 % 10 = 5
So 928148-80-5 is a valid CAS Registry Number.
