Check Digit Verification of cas no
The CAS Registry Mumber 437999-44-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,3,7,9,9 and 9 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 437999-44:
(8*4)+(7*3)+(6*7)+(5*9)+(4*9)+(3*9)+(2*4)+(1*4)=215
215 % 10 = 5
So 437999-44-5 is a valid CAS Registry Number.
