179754-21-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 179754-21-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,9,7,5 and 4 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 179754-21:
(8*1)+(7*7)+(6*9)+(5*7)+(4*5)+(3*4)+(2*2)+(1*1)=183
183 % 10 = 3
So 179754-21-3 is a valid CAS Registry Number.
