90381-72-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 90381-72-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,3,8 and 1 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 90381-72:
(7*9)+(6*0)+(5*3)+(4*8)+(3*1)+(2*7)+(1*2)=129
129 % 10 = 9
So 90381-72-9 is a valid CAS Registry Number.
