213380-73-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 213380-73-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,3,3,8 and 0 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 213380-73:
(8*2)+(7*1)+(6*3)+(5*3)+(4*8)+(3*0)+(2*7)+(1*3)=105
105 % 10 = 5
So 213380-73-5 is a valid CAS Registry Number.
