Check Digit Verification of cas no
The CAS Registry Mumber 1324-57-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,3,2 and 4 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1324-57:
(6*1)+(5*3)+(4*2)+(3*4)+(2*5)+(1*7)=58
58 % 10 = 8
So 1324-57-8 is a valid CAS Registry Number.
