Check Digit Verification of cas no
The CAS Registry Mumber 204254-92-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,4,2,5 and 4 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 204254-92:
(8*2)+(7*0)+(6*4)+(5*2)+(4*5)+(3*4)+(2*9)+(1*2)=102
102 % 10 = 2
So 204254-92-2 is a valid CAS Registry Number.
