141242-73-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 141242-73-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,1,2,4 and 2 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 141242-73:
(8*1)+(7*4)+(6*1)+(5*2)+(4*4)+(3*2)+(2*7)+(1*3)=91
91 % 10 = 1
So 141242-73-1 is a valid CAS Registry Number.
