215920-83-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 215920-83-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,5,9,2 and 0 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 215920-83:
(8*2)+(7*1)+(6*5)+(5*9)+(4*2)+(3*0)+(2*8)+(1*3)=125
125 % 10 = 5
So 215920-83-5 is a valid CAS Registry Number.
