19797-84-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 19797-84-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,7,9 and 7 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 19797-84:
(7*1)+(6*9)+(5*7)+(4*9)+(3*7)+(2*8)+(1*4)=173
173 % 10 = 3
So 19797-84-3 is a valid CAS Registry Number.
