141398-84-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 141398-84-7 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, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 141398-84:
(8*1)+(7*4)+(6*1)+(5*3)+(4*9)+(3*8)+(2*8)+(1*4)=137
137 % 10 = 7
So 141398-84-7 is a valid CAS Registry Number.
