143949-26-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 143949-26-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,9,4 and 9 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 143949-26:
(8*1)+(7*4)+(6*3)+(5*9)+(4*4)+(3*9)+(2*2)+(1*6)=152
152 % 10 = 2
So 143949-26-2 is a valid CAS Registry Number.
