Check Digit Verification of cas no
The CAS Registry Mumber 740083-57-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,4,0,0,8 and 3 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 740083-57:
(8*7)+(7*4)+(6*0)+(5*0)+(4*8)+(3*3)+(2*5)+(1*7)=142
142 % 10 = 2
So 740083-57-2 is a valid CAS Registry Number.
