186258-20-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 186258-20-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,6,2,5 and 8 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 186258-20:
(8*1)+(7*8)+(6*6)+(5*2)+(4*5)+(3*8)+(2*2)+(1*0)=158
158 % 10 = 8
So 186258-20-8 is a valid CAS Registry Number.
