Check Digit Verification of cas no
The CAS Registry Mumber 751-83-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,5 and 1 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 751-83:
(5*7)+(4*5)+(3*1)+(2*8)+(1*3)=77
77 % 10 = 7
So 751-83-7 is a valid CAS Registry Number.
