Check Digit Verification of cas no
The CAS Registry Mumber 2841-38-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,8,4 and 1 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 2841-38:
(6*2)+(5*8)+(4*4)+(3*1)+(2*3)+(1*8)=85
85 % 10 = 5
So 2841-38-5 is a valid CAS Registry Number.
