42492-21-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 42492-21-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,4,9 and 2 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 42492-21:
(7*4)+(6*2)+(5*4)+(4*9)+(3*2)+(2*2)+(1*1)=107
107 % 10 = 7
So 42492-21-7 is a valid CAS Registry Number.
