121769-69-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 121769-69-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,7,6 and 9 respectively; the second part has 2 digits, 6 and 9 respectively.Calculate Digit Verification of CAS Registry Number 121769-69:
(8*1)+(7*2)+(6*1)+(5*7)+(4*6)+(3*9)+(2*6)+(1*9)=135
135 % 10 = 5
So 121769-69-5 is a valid CAS Registry Number.
