90909-52-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 90909-52-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,9,0 and 9 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 90909-52:
(7*9)+(6*0)+(5*9)+(4*0)+(3*9)+(2*5)+(1*2)=147
147 % 10 = 7
So 90909-52-7 is a valid CAS Registry Number.
