109229-15-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 109229-15-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,2,2 and 9 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 109229-15:
(8*1)+(7*0)+(6*9)+(5*2)+(4*2)+(3*9)+(2*1)+(1*5)=114
114 % 10 = 4
So 109229-15-4 is a valid CAS Registry Number.
