944583-37-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 944583-37-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,4,5,8 and 3 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 944583-37:
(8*9)+(7*4)+(6*4)+(5*5)+(4*8)+(3*3)+(2*3)+(1*7)=203
203 % 10 = 3
So 944583-37-3 is a valid CAS Registry Number.
