Check Digit Verification of cas no
The CAS Registry Mumber 3838-05-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,8,3 and 8 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 3838-05:
(6*3)+(5*8)+(4*3)+(3*8)+(2*0)+(1*5)=99
99 % 10 = 9
So 3838-05-9 is a valid CAS Registry Number.
