203797-90-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 203797-90-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,3,7,9 and 7 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 203797-90:
(8*2)+(7*0)+(6*3)+(5*7)+(4*9)+(3*7)+(2*9)+(1*0)=144
144 % 10 = 4
So 203797-90-4 is a valid CAS Registry Number.
