174221-81-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 174221-81-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,4,2,2 and 1 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 174221-81:
(8*1)+(7*7)+(6*4)+(5*2)+(4*2)+(3*1)+(2*8)+(1*1)=119
119 % 10 = 9
So 174221-81-9 is a valid CAS Registry Number.
