Check Digit Verification of cas no
The CAS Registry Mumber 1321-57-9 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 1 respectively; the second part has 2 digits, 5 and 7 respectively.Calculate Digit Verification of CAS Registry Number 1321-57:
(6*1)+(5*3)+(4*2)+(3*1)+(2*5)+(1*7)=49
49 % 10 = 9
So 1321-57-9 is a valid CAS Registry Number.
