427880-47-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 427880-47-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,2,7,8,8 and 0 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 427880-47:
(8*4)+(7*2)+(6*7)+(5*8)+(4*8)+(3*0)+(2*4)+(1*7)=175
175 % 10 = 5
So 427880-47-5 is a valid CAS Registry Number.
