88909-19-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 88909-19-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,8,9,0 and 9 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 88909-19:
(7*8)+(6*8)+(5*9)+(4*0)+(3*9)+(2*1)+(1*9)=187
187 % 10 = 7
So 88909-19-7 is a valid CAS Registry Number.
