746638-49-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 746638-49-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,4,6,6,3 and 8 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 746638-49:
(8*7)+(7*4)+(6*6)+(5*6)+(4*3)+(3*8)+(2*4)+(1*9)=203
203 % 10 = 3
So 746638-49-3 is a valid CAS Registry Number.
