79970-24-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 79970-24-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,9,7 and 0 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 79970-24:
(7*7)+(6*9)+(5*9)+(4*7)+(3*0)+(2*2)+(1*4)=184
184 % 10 = 4
So 79970-24-4 is a valid CAS Registry Number.
