141945-40-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 141945-40-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,1,9,4 and 5 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 141945-40:
(8*1)+(7*4)+(6*1)+(5*9)+(4*4)+(3*5)+(2*4)+(1*0)=126
126 % 10 = 6
So 141945-40-6 is a valid CAS Registry Number.
