142603-49-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 142603-49-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,6,0 and 3 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 142603-49:
(8*1)+(7*4)+(6*2)+(5*6)+(4*0)+(3*3)+(2*4)+(1*9)=104
104 % 10 = 4
So 142603-49-4 is a valid CAS Registry Number.
