Check Digit Verification of cas no
The CAS Registry Mumber 4721-36-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,7,2 and 1 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 4721-36:
(6*4)+(5*7)+(4*2)+(3*1)+(2*3)+(1*6)=82
82 % 10 = 2
So 4721-36-2 is a valid CAS Registry Number.
