7216-63-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 7216-63-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,2,1 and 6 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 7216-63:
(6*7)+(5*2)+(4*1)+(3*6)+(2*6)+(1*3)=89
89 % 10 = 9
So 7216-63-9 is a valid CAS Registry Number.
