176208-18-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 176208-18-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,6,2,0 and 8 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 176208-18:
(8*1)+(7*7)+(6*6)+(5*2)+(4*0)+(3*8)+(2*1)+(1*8)=137
137 % 10 = 7
So 176208-18-7 is a valid CAS Registry Number.
