215257-48-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 215257-48-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,5,2,5 and 7 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 215257-48:
(8*2)+(7*1)+(6*5)+(5*2)+(4*5)+(3*7)+(2*4)+(1*8)=120
120 % 10 = 0
So 215257-48-0 is a valid CAS Registry Number.
