239474-55-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 239474-55-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,3,9,4,7 and 4 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 239474-55:
(8*2)+(7*3)+(6*9)+(5*4)+(4*7)+(3*4)+(2*5)+(1*5)=166
166 % 10 = 6
So 239474-55-6 is a valid CAS Registry Number.
