82957-84-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 82957-84-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,9,5 and 7 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 82957-84:
(7*8)+(6*2)+(5*9)+(4*5)+(3*7)+(2*8)+(1*4)=174
174 % 10 = 4
So 82957-84-4 is a valid CAS Registry Number.
