174902-16-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 174902-16-0 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 6 respectively.
Calculate Digit Verification of CAS Registry Number 174902-16:
(8*1)+(7*7)+(6*4)+(5*9)+(4*0)+(3*2)+(2*1)+(1*6)=140
140 % 10 = 0
So 174902-16-0 is a valid CAS Registry Number.
