28519-33-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 28519-33-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,5,1 and 9 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 28519-33:
(7*2)+(6*8)+(5*5)+(4*1)+(3*9)+(2*3)+(1*3)=127
127 % 10 = 7
So 28519-33-7 is a valid CAS Registry Number.
