207223-28-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 207223-28-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,7,2,2 and 3 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 207223-28:
(8*2)+(7*0)+(6*7)+(5*2)+(4*2)+(3*3)+(2*2)+(1*8)=97
97 % 10 = 7
So 207223-28-7 is a valid CAS Registry Number.
