Flammability and Explosibility

Notclassified

Check Digit Verification of cas no

The CAS Registry Mumber 90-51-7 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 9 and 0 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 90-51:
(4*9)+(3*0)+(2*5)+(1*1)=47
47 % 10 = 7
So 90-51-7 is a valid CAS Registry Number.
