217184-40-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 217184-40-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,7,1,8 and 4 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 217184-40:
(8*2)+(7*1)+(6*7)+(5*1)+(4*8)+(3*4)+(2*4)+(1*0)=122
122 % 10 = 2
So 217184-40-2 is a valid CAS Registry Number.
