66820-38-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 66820-38-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,8,2 and 0 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 66820-38:
(7*6)+(6*6)+(5*8)+(4*2)+(3*0)+(2*3)+(1*8)=140
140 % 10 = 0
So 66820-38-0 is a valid CAS Registry Number.
