178552-18-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 178552-18-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,8,5,5 and 2 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 178552-18:
(8*1)+(7*7)+(6*8)+(5*5)+(4*5)+(3*2)+(2*1)+(1*8)=166
166 % 10 = 6
So 178552-18-6 is a valid CAS Registry Number.
