80948-11-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 80948-11-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,9,4 and 8 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 80948-11:
(7*8)+(6*0)+(5*9)+(4*4)+(3*8)+(2*1)+(1*1)=144
144 % 10 = 4
So 80948-11-4 is a valid CAS Registry Number.
