478496-90-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 478496-90-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,8,4,9 and 6 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 478496-90:
(8*4)+(7*7)+(6*8)+(5*4)+(4*9)+(3*6)+(2*9)+(1*0)=221
221 % 10 = 1
So 478496-90-1 is a valid CAS Registry Number.
