42879-03-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 42879-03-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,8,7 and 9 respectively; the second part has 2 digits, 0 and 3 respectively.Calculate Digit Verification of CAS Registry Number 42879-03:
(7*4)+(6*2)+(5*8)+(4*7)+(3*9)+(2*0)+(1*3)=138
138 % 10 = 8
So 42879-03-8 is a valid CAS Registry Number.
