141855-80-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 141855-80-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,1,8,5 and 5 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 141855-80:
(8*1)+(7*4)+(6*1)+(5*8)+(4*5)+(3*5)+(2*8)+(1*0)=133
133 % 10 = 3
So 141855-80-3 is a valid CAS Registry Number.
