172476-73-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 172476-73-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,2,4,7 and 6 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 172476-73:
(8*1)+(7*7)+(6*2)+(5*4)+(4*7)+(3*6)+(2*7)+(1*3)=152
152 % 10 = 2
So 172476-73-2 is a valid CAS Registry Number.
