170991-12-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 170991-12-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,0,9,9 and 1 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 170991-12:
(8*1)+(7*7)+(6*0)+(5*9)+(4*9)+(3*1)+(2*1)+(1*2)=145
145 % 10 = 5
So 170991-12-5 is a valid CAS Registry Number.
