1849-05-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1849-05-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,4 and 9 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1849-05:
(6*1)+(5*8)+(4*4)+(3*9)+(2*0)+(1*5)=94
94 % 10 = 4
So 1849-05-4 is a valid CAS Registry Number.
