141398-79-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 141398-79-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,1,3,9 and 8 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 141398-79:
(8*1)+(7*4)+(6*1)+(5*3)+(4*9)+(3*8)+(2*7)+(1*9)=140
140 % 10 = 0
So 141398-79-0 is a valid CAS Registry Number.
