126378-46-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 126378-46-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,3,7 and 8 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 126378-46:
(8*1)+(7*2)+(6*6)+(5*3)+(4*7)+(3*8)+(2*4)+(1*6)=139
139 % 10 = 9
So 126378-46-9 is a valid CAS Registry Number.
