218786-09-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 218786-09-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,8,7,8 and 6 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 218786-09:
(8*2)+(7*1)+(6*8)+(5*7)+(4*8)+(3*6)+(2*0)+(1*9)=165
165 % 10 = 5
So 218786-09-5 is a valid CAS Registry Number.
