140870-47-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 140870-47-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,8,7 and 0 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 140870-47:
(8*1)+(7*4)+(6*0)+(5*8)+(4*7)+(3*0)+(2*4)+(1*7)=119
119 % 10 = 9
So 140870-47-9 is a valid CAS Registry Number.
