141945-36-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 141945-36-0 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, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 141945-36:
(8*1)+(7*4)+(6*1)+(5*9)+(4*4)+(3*5)+(2*3)+(1*6)=130
130 % 10 = 0
So 141945-36-0 is a valid CAS Registry Number.
