214556-63-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 214556-63-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,4,5,5 and 6 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 214556-63:
(8*2)+(7*1)+(6*4)+(5*5)+(4*5)+(3*6)+(2*6)+(1*3)=125
125 % 10 = 5
So 214556-63-5 is a valid CAS Registry Number.
