117668-87-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 117668-87-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,6,6 and 8 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 117668-87:
(8*1)+(7*1)+(6*7)+(5*6)+(4*6)+(3*8)+(2*8)+(1*7)=158
158 % 10 = 8
So 117668-87-8 is a valid CAS Registry Number.
