297750-32-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 297750-32-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,9,7,7,5 and 0 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 297750-32:
(8*2)+(7*9)+(6*7)+(5*7)+(4*5)+(3*0)+(2*3)+(1*2)=184
184 % 10 = 4
So 297750-32-4 is a valid CAS Registry Number.
