1948-02-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1948-02-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,9,4 and 8 respectively; the second part has 2 digits, 0 and 2 respectively.Calculate Digit Verification of CAS Registry Number 1948-02:
(6*1)+(5*9)+(4*4)+(3*8)+(2*0)+(1*2)=93
93 % 10 = 3
So 1948-02-3 is a valid CAS Registry Number.
