390790-80-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 390790-80-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,9,0,7,9 and 0 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 390790-80:
(8*3)+(7*9)+(6*0)+(5*7)+(4*9)+(3*0)+(2*8)+(1*0)=174
174 % 10 = 4
So 390790-80-4 is a valid CAS Registry Number.
