94274-63-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 94274-63-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,4,2,7 and 4 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 94274-63:
(7*9)+(6*4)+(5*2)+(4*7)+(3*4)+(2*6)+(1*3)=152
152 % 10 = 2
So 94274-63-2 is a valid CAS Registry Number.
