206191-15-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 206191-15-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,6,1,9 and 1 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 206191-15:
(8*2)+(7*0)+(6*6)+(5*1)+(4*9)+(3*1)+(2*1)+(1*5)=103
103 % 10 = 3
So 206191-15-3 is a valid CAS Registry Number.
