490021-01-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 490021-01-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,9,0,0,2 and 1 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 490021-01:
(8*4)+(7*9)+(6*0)+(5*0)+(4*2)+(3*1)+(2*0)+(1*1)=107
107 % 10 = 7
So 490021-01-7 is a valid CAS Registry Number.
