174902-17-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 174902-17-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,4,9,0 and 2 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 174902-17:
(8*1)+(7*7)+(6*4)+(5*9)+(4*0)+(3*2)+(2*1)+(1*7)=141
141 % 10 = 1
So 174902-17-1 is a valid CAS Registry Number.
