177904-42-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 177904-42-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,7,9,0 and 4 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 177904-42:
(8*1)+(7*7)+(6*7)+(5*9)+(4*0)+(3*4)+(2*4)+(1*2)=166
166 % 10 = 6
So 177904-42-6 is a valid CAS Registry Number.
