205587-47-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 205587-47-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,5,5,8 and 7 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 205587-47:
(8*2)+(7*0)+(6*5)+(5*5)+(4*8)+(3*7)+(2*4)+(1*7)=139
139 % 10 = 9
So 205587-47-9 is a valid CAS Registry Number.
