Check Digit Verification of cas no
The CAS Registry Mumber 2737-20-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,7,3 and 7 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 2737-20:
(6*2)+(5*7)+(4*3)+(3*7)+(2*2)+(1*0)=84
84 % 10 = 4
So 2737-20-4 is a valid CAS Registry Number.
