105199-81-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 105199-81-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,5,1,9 and 9 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 105199-81:
(8*1)+(7*0)+(6*5)+(5*1)+(4*9)+(3*9)+(2*8)+(1*1)=123
123 % 10 = 3
So 105199-81-3 is a valid CAS Registry Number.
