269397-84-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 269397-84-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,9,3,9 and 7 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 269397-84:
(8*2)+(7*6)+(6*9)+(5*3)+(4*9)+(3*7)+(2*8)+(1*4)=204
204 % 10 = 4
So 269397-84-4 is a valid CAS Registry Number.
