4206-15-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 4206-15-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,0 and 6 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 4206-15:
(6*4)+(5*2)+(4*0)+(3*6)+(2*1)+(1*5)=59
59 % 10 = 9
So 4206-15-9 is a valid CAS Registry Number.
