140477-28-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 140477-28-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,4,7 and 7 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 140477-28:
(8*1)+(7*4)+(6*0)+(5*4)+(4*7)+(3*7)+(2*2)+(1*8)=117
117 % 10 = 7
So 140477-28-7 is a valid CAS Registry Number.
