111872-69-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 111872-69-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,8,7 and 2 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 111872-69:
(8*1)+(7*1)+(6*1)+(5*8)+(4*7)+(3*2)+(2*6)+(1*9)=116
116 % 10 = 6
So 111872-69-6 is a valid CAS Registry Number.
