279220-02-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 279220-02-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,7,9,2,2 and 0 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 279220-02:
(8*2)+(7*7)+(6*9)+(5*2)+(4*2)+(3*0)+(2*0)+(1*2)=139
139 % 10 = 9
So 279220-02-9 is a valid CAS Registry Number.
