85840-18-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 85840-18-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,8,4 and 0 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 85840-18:
(7*8)+(6*5)+(5*8)+(4*4)+(3*0)+(2*1)+(1*8)=152
152 % 10 = 2
So 85840-18-2 is a valid CAS Registry Number.
