78023-66-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 78023-66-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,0,2 and 3 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 78023-66:
(7*7)+(6*8)+(5*0)+(4*2)+(3*3)+(2*6)+(1*6)=132
132 % 10 = 2
So 78023-66-2 is a valid CAS Registry Number.
