84042-26-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 84042-26-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,0,4 and 2 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 84042-26:
(7*8)+(6*4)+(5*0)+(4*4)+(3*2)+(2*2)+(1*6)=112
112 % 10 = 2
So 84042-26-2 is a valid CAS Registry Number.
