Check Digit Verification of cas no
The CAS Registry Mumber 906673-54-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,6,6,7 and 3 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 906673-54:
(8*9)+(7*0)+(6*6)+(5*6)+(4*7)+(3*3)+(2*5)+(1*4)=189
189 % 10 = 9
So 906673-54-9 is a valid CAS Registry Number.
