90305-08-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 90305-08-1 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 5 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 90305-08:
(7*9)+(6*0)+(5*3)+(4*0)+(3*5)+(2*0)+(1*8)=101
101 % 10 = 1
So 90305-08-1 is a valid CAS Registry Number.
