79870-11-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 79870-11-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,8,7 and 0 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 79870-11:
(7*7)+(6*9)+(5*8)+(4*7)+(3*0)+(2*1)+(1*1)=174
174 % 10 = 4
So 79870-11-4 is a valid CAS Registry Number.
