2159-32-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 2159-32-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,5 and 9 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 2159-32:
(6*2)+(5*1)+(4*5)+(3*9)+(2*3)+(1*2)=72
72 % 10 = 2
So 2159-32-2 is a valid CAS Registry Number.
