127879-26-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 127879-26-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,8,7 and 9 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 127879-26:
(8*1)+(7*2)+(6*7)+(5*8)+(4*7)+(3*9)+(2*2)+(1*6)=169
169 % 10 = 9
So 127879-26-9 is a valid CAS Registry Number.
