185026-91-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 185026-91-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,5,0,2 and 6 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 185026-91:
(8*1)+(7*8)+(6*5)+(5*0)+(4*2)+(3*6)+(2*9)+(1*1)=139
139 % 10 = 9
So 185026-91-9 is a valid CAS Registry Number.
