111854-25-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 111854-25-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,8,5 and 4 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 111854-25:
(8*1)+(7*1)+(6*1)+(5*8)+(4*5)+(3*4)+(2*2)+(1*5)=102
102 % 10 = 2
So 111854-25-2 is a valid CAS Registry Number.
