1929-56-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1929-56-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,9,2 and 9 respectively; the second part has 2 digits, 5 and 6 respectively.Calculate Digit Verification of CAS Registry Number 1929-56:
(6*1)+(5*9)+(4*2)+(3*9)+(2*5)+(1*6)=102
102 % 10 = 2
So 1929-56-2 is a valid CAS Registry Number.
