70997-70-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 70997-70-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,9,9 and 7 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 70997-70:
(7*7)+(6*0)+(5*9)+(4*9)+(3*7)+(2*7)+(1*0)=165
165 % 10 = 5
So 70997-70-5 is a valid CAS Registry Number.
