171048-61-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 171048-61-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,1,0,4 and 8 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 171048-61:
(8*1)+(7*7)+(6*1)+(5*0)+(4*4)+(3*8)+(2*6)+(1*1)=116
116 % 10 = 6
So 171048-61-6 is a valid CAS Registry Number.
