66641-63-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 66641-63-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,6,4 and 1 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 66641-63:
(7*6)+(6*6)+(5*6)+(4*4)+(3*1)+(2*6)+(1*3)=142
142 % 10 = 2
So 66641-63-2 is a valid CAS Registry Number.
