171924-20-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 171924-20-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,1,9,2 and 4 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 171924-20:
(8*1)+(7*7)+(6*1)+(5*9)+(4*2)+(3*4)+(2*2)+(1*0)=132
132 % 10 = 2
So 171924-20-2 is a valid CAS Registry Number.
