436143-88-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 436143-88-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,3,6,1,4 and 3 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 436143-88:
(8*4)+(7*3)+(6*6)+(5*1)+(4*4)+(3*3)+(2*8)+(1*8)=143
143 % 10 = 3
So 436143-88-3 is a valid CAS Registry Number.
