Check Digit Verification of cas no
The CAS Registry Mumber 7045-83-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,0,4 and 5 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 7045-83:
(6*7)+(5*0)+(4*4)+(3*5)+(2*8)+(1*3)=92
92 % 10 = 2
So 7045-83-2 is a valid CAS Registry Number.
