85992-27-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 85992-27-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,9,9 and 2 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 85992-27:
(7*8)+(6*5)+(5*9)+(4*9)+(3*2)+(2*2)+(1*7)=184
184 % 10 = 4
So 85992-27-4 is a valid CAS Registry Number.
