217973-63-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 217973-63-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,7,9,7 and 3 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 217973-63:
(8*2)+(7*1)+(6*7)+(5*9)+(4*7)+(3*3)+(2*6)+(1*3)=162
162 % 10 = 2
So 217973-63-2 is a valid CAS Registry Number.
