90396-11-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 90396-11-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,3,9 and 6 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 90396-11:
(7*9)+(6*0)+(5*3)+(4*9)+(3*6)+(2*1)+(1*1)=135
135 % 10 = 5
So 90396-11-5 is a valid CAS Registry Number.
