90511-04-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 90511-04-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,5,1 and 1 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 90511-04:
(7*9)+(6*0)+(5*5)+(4*1)+(3*1)+(2*0)+(1*4)=99
99 % 10 = 9
So 90511-04-9 is a valid CAS Registry Number.
