174022-40-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 174022-40-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,4,0,2 and 2 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 174022-40:
(8*1)+(7*7)+(6*4)+(5*0)+(4*2)+(3*2)+(2*4)+(1*0)=103
103 % 10 = 3
So 174022-40-3 is a valid CAS Registry Number.
