153901-53-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 153901-53-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,3,9,0 and 1 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 153901-53:
(8*1)+(7*5)+(6*3)+(5*9)+(4*0)+(3*1)+(2*5)+(1*3)=122
122 % 10 = 2
So 153901-53-2 is a valid CAS Registry Number.
