321592-94-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 321592-94-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,2,1,5,9 and 2 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 321592-94:
(8*3)+(7*2)+(6*1)+(5*5)+(4*9)+(3*2)+(2*9)+(1*4)=133
133 % 10 = 3
So 321592-94-3 is a valid CAS Registry Number.
