Check Digit Verification of cas no
The CAS Registry Mumber 7736-43-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,3 and 6 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 7736-43:
(6*7)+(5*7)+(4*3)+(3*6)+(2*4)+(1*3)=118
118 % 10 = 8
So 7736-43-8 is a valid CAS Registry Number.
