111980-33-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 111980-33-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,9,8 and 0 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 111980-33:
(8*1)+(7*1)+(6*1)+(5*9)+(4*8)+(3*0)+(2*3)+(1*3)=107
107 % 10 = 7
So 111980-33-7 is a valid CAS Registry Number.
