85784-70-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 85784-70-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,7,8 and 4 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 85784-70:
(7*8)+(6*5)+(5*7)+(4*8)+(3*4)+(2*7)+(1*0)=179
179 % 10 = 9
So 85784-70-9 is a valid CAS Registry Number.
