Check Digit Verification of cas no
The CAS Registry Mumber 20380-19-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,3,8 and 0 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 20380-19:
(7*2)+(6*0)+(5*3)+(4*8)+(3*0)+(2*1)+(1*9)=72
72 % 10 = 2
So 20380-19-2 is a valid CAS Registry Number.
