756894-33-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 756894-33-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,5,6,8,9 and 4 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 756894-33:
(8*7)+(7*5)+(6*6)+(5*8)+(4*9)+(3*4)+(2*3)+(1*3)=224
224 % 10 = 4
So 756894-33-4 is a valid CAS Registry Number.
