133522-14-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 133522-14-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,5,2 and 2 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 133522-14:
(8*1)+(7*3)+(6*3)+(5*5)+(4*2)+(3*2)+(2*1)+(1*4)=92
92 % 10 = 2
So 133522-14-2 is a valid CAS Registry Number.
