417701-84-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 417701-84-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,1,7,7,0 and 1 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 417701-84:
(8*4)+(7*1)+(6*7)+(5*7)+(4*0)+(3*1)+(2*8)+(1*4)=139
139 % 10 = 9
So 417701-84-9 is a valid CAS Registry Number.
