79139-90-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 79139-90-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,1,3 and 9 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 79139-90:
(7*7)+(6*9)+(5*1)+(4*3)+(3*9)+(2*9)+(1*0)=165
165 % 10 = 5
So 79139-90-5 is a valid CAS Registry Number.
