116428-62-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 116428-62-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,6,4,2 and 8 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 116428-62:
(8*1)+(7*1)+(6*6)+(5*4)+(4*2)+(3*8)+(2*6)+(1*2)=117
117 % 10 = 7
So 116428-62-7 is a valid CAS Registry Number.
