27448-82-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 27448-82-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,4,4 and 8 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 27448-82:
(7*2)+(6*7)+(5*4)+(4*4)+(3*8)+(2*8)+(1*2)=134
134 % 10 = 4
So 27448-82-4 is a valid CAS Registry Number.
