90133-51-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 90133-51-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,1,3 and 3 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 90133-51:
(7*9)+(6*0)+(5*1)+(4*3)+(3*3)+(2*5)+(1*1)=100
100 % 10 = 0
So 90133-51-0 is a valid CAS Registry Number.
