904684-28-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 904684-28-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,4,6,8 and 4 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 904684-28:
(8*9)+(7*0)+(6*4)+(5*6)+(4*8)+(3*4)+(2*2)+(1*8)=182
182 % 10 = 2
So 904684-28-2 is a valid CAS Registry Number.
