80421-74-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 80421-74-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,4,2 and 1 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 80421-74:
(7*8)+(6*0)+(5*4)+(4*2)+(3*1)+(2*7)+(1*4)=105
105 % 10 = 5
So 80421-74-5 is a valid CAS Registry Number.
