186966-08-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 186966-08-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,6,9,6 and 6 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 186966-08:
(8*1)+(7*8)+(6*6)+(5*9)+(4*6)+(3*6)+(2*0)+(1*8)=195
195 % 10 = 5
So 186966-08-5 is a valid CAS Registry Number.
