90358-65-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 90358-65-9 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 8 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 90358-65:
(7*9)+(6*0)+(5*3)+(4*5)+(3*8)+(2*6)+(1*5)=139
139 % 10 = 9
So 90358-65-9 is a valid CAS Registry Number.
