850026-91-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 850026-91-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,0,0,2 and 6 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 850026-91:
(8*8)+(7*5)+(6*0)+(5*0)+(4*2)+(3*6)+(2*9)+(1*1)=144
144 % 10 = 4
So 850026-91-4 is a valid CAS Registry Number.
