1493-52-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1493-52-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,4,9 and 3 respectively; the second part has 2 digits, 5 and 2 respectively.Calculate Digit Verification of CAS Registry Number 1493-52:
(6*1)+(5*4)+(4*9)+(3*3)+(2*5)+(1*2)=83
83 % 10 = 3
So 1493-52-3 is a valid CAS Registry Number.
