141726-92-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 141726-92-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,1,7,2 and 6 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 141726-92:
(8*1)+(7*4)+(6*1)+(5*7)+(4*2)+(3*6)+(2*9)+(1*2)=123
123 % 10 = 3
So 141726-92-3 is a valid CAS Registry Number.
