90355-26-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 90355-26-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,3,5 and 5 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 90355-26:
(7*9)+(6*0)+(5*3)+(4*5)+(3*5)+(2*2)+(1*6)=123
123 % 10 = 3
So 90355-26-3 is a valid CAS Registry Number.
