88730-70-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 88730-70-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,8,7,3 and 0 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 88730-70:
(7*8)+(6*8)+(5*7)+(4*3)+(3*0)+(2*7)+(1*0)=165
165 % 10 = 5
So 88730-70-5 is a valid CAS Registry Number.
