80446-23-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 80446-23-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,4,4 and 6 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 80446-23:
(7*8)+(6*0)+(5*4)+(4*4)+(3*6)+(2*2)+(1*3)=117
117 % 10 = 7
So 80446-23-7 is a valid CAS Registry Number.
