140836-57-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 140836-57-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,8,3 and 6 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 140836-57:
(8*1)+(7*4)+(6*0)+(5*8)+(4*3)+(3*6)+(2*5)+(1*7)=123
123 % 10 = 3
So 140836-57-3 is a valid CAS Registry Number.
