811807-99-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 811807-99-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,1,1,8,0 and 7 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 811807-99:
(8*8)+(7*1)+(6*1)+(5*8)+(4*0)+(3*7)+(2*9)+(1*9)=165
165 % 10 = 5
So 811807-99-5 is a valid CAS Registry Number.
