127718-19-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 127718-19-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,7,1 and 8 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 127718-19:
(8*1)+(7*2)+(6*7)+(5*7)+(4*1)+(3*8)+(2*1)+(1*9)=138
138 % 10 = 8
So 127718-19-8 is a valid CAS Registry Number.
