Check Digit Verification of cas no
The CAS Registry Mumber 4378-40-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,3,7 and 8 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 4378-40:
(6*4)+(5*3)+(4*7)+(3*8)+(2*4)+(1*0)=99
99 % 10 = 9
So 4378-40-9 is a valid CAS Registry Number.
