437703-13-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 437703-13-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,3,7,7,0 and 3 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 437703-13:
(8*4)+(7*3)+(6*7)+(5*7)+(4*0)+(3*3)+(2*1)+(1*3)=144
144 % 10 = 4
So 437703-13-4 is a valid CAS Registry Number.
