220697-78-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 220697-78-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,6,9 and 7 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 220697-78:
(8*2)+(7*2)+(6*0)+(5*6)+(4*9)+(3*7)+(2*7)+(1*8)=139
139 % 10 = 9
So 220697-78-9 is a valid CAS Registry Number.
