140887-40-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 140887-40-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,8,8 and 7 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 140887-40:
(8*1)+(7*4)+(6*0)+(5*8)+(4*8)+(3*7)+(2*4)+(1*0)=137
137 % 10 = 7
So 140887-40-7 is a valid CAS Registry Number.
