186791-40-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 186791-40-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,6,7,9 and 1 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 186791-40:
(8*1)+(7*8)+(6*6)+(5*7)+(4*9)+(3*1)+(2*4)+(1*0)=182
182 % 10 = 2
So 186791-40-2 is a valid CAS Registry Number.
