842127-57-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 842127-57-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,2,1,2 and 7 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 842127-57:
(8*8)+(7*4)+(6*2)+(5*1)+(4*2)+(3*7)+(2*5)+(1*7)=155
155 % 10 = 5
So 842127-57-5 is a valid CAS Registry Number.
