49648-37-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 49648-37-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,9,6,4 and 8 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 49648-37:
(7*4)+(6*9)+(5*6)+(4*4)+(3*8)+(2*3)+(1*7)=165
165 % 10 = 5
So 49648-37-5 is a valid CAS Registry Number.
