141075-46-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 141075-46-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,1,0,7 and 5 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 141075-46:
(8*1)+(7*4)+(6*1)+(5*0)+(4*7)+(3*5)+(2*4)+(1*6)=99
99 % 10 = 9
So 141075-46-9 is a valid CAS Registry Number.
