Check Digit Verification of cas no
The CAS Registry Mumber 38943-76-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,8,9,4 and 3 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 38943-76:
(7*3)+(6*8)+(5*9)+(4*4)+(3*3)+(2*7)+(1*6)=159
159 % 10 = 9
So 38943-76-9 is a valid CAS Registry Number.
