90304-36-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 90304-36-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,3,0 and 4 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 90304-36:
(7*9)+(6*0)+(5*3)+(4*0)+(3*4)+(2*3)+(1*6)=102
102 % 10 = 2
So 90304-36-2 is a valid CAS Registry Number.
