957323-40-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 957323-40-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,5,7,3,2 and 3 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 957323-40:
(8*9)+(7*5)+(6*7)+(5*3)+(4*2)+(3*3)+(2*4)+(1*0)=189
189 % 10 = 9
So 957323-40-9 is a valid CAS Registry Number.
