Flammability and Explosibility
Notclassified
Check Digit Verification of cas no
The CAS Registry Mumber 28983-56-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,9,8 and 3 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 28983-56:
(7*2)+(6*8)+(5*9)+(4*8)+(3*3)+(2*5)+(1*6)=164
164 % 10 = 4
So 28983-56-4 is a valid CAS Registry Number.
