479633-91-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 479633-91-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,9,6,3 and 3 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 479633-91:
(8*4)+(7*7)+(6*9)+(5*6)+(4*3)+(3*3)+(2*9)+(1*1)=205
205 % 10 = 5
So 479633-91-5 is a valid CAS Registry Number.
