79970-23-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 79970-23-3 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 3 respectively.
Calculate Digit Verification of CAS Registry Number 79970-23:
(7*7)+(6*9)+(5*9)+(4*7)+(3*0)+(2*2)+(1*3)=183
183 % 10 = 3
So 79970-23-3 is a valid CAS Registry Number.
