279259-19-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 279259-19-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,7,9,2,5 and 9 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 279259-19:
(8*2)+(7*7)+(6*9)+(5*2)+(4*5)+(3*9)+(2*1)+(1*9)=187
187 % 10 = 7
So 279259-19-7 is a valid CAS Registry Number.
