2205-92-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 2205-92-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,2,0 and 5 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 2205-92:
(6*2)+(5*2)+(4*0)+(3*5)+(2*9)+(1*2)=57
57 % 10 = 7
So 2205-92-7 is a valid CAS Registry Number.
