105728-99-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 105728-99-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,5,7,2 and 8 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 105728-99:
(8*1)+(7*0)+(6*5)+(5*7)+(4*2)+(3*8)+(2*9)+(1*9)=132
132 % 10 = 2
So 105728-99-2 is a valid CAS Registry Number.
