728948-82-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 728948-82-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,2,8,9,4 and 8 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 728948-82:
(8*7)+(7*2)+(6*8)+(5*9)+(4*4)+(3*8)+(2*8)+(1*2)=221
221 % 10 = 1
So 728948-82-1 is a valid CAS Registry Number.
