105729-01-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 105729-01-9 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 9 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 105729-01:
(8*1)+(7*0)+(6*5)+(5*7)+(4*2)+(3*9)+(2*0)+(1*1)=109
109 % 10 = 9
So 105729-01-9 is a valid CAS Registry Number.
