19432-37-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 19432-37-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,4,3 and 2 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 19432-37:
(7*1)+(6*9)+(5*4)+(4*3)+(3*2)+(2*3)+(1*7)=112
112 % 10 = 2
So 19432-37-2 is a valid CAS Registry Number.
