156406-28-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 156406-28-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,4,0 and 6 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 156406-28:
(8*1)+(7*5)+(6*6)+(5*4)+(4*0)+(3*6)+(2*2)+(1*8)=129
129 % 10 = 9
So 156406-28-9 is a valid CAS Registry Number.
