134649-61-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 134649-61-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,6,4 and 9 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 134649-61:
(8*1)+(7*3)+(6*4)+(5*6)+(4*4)+(3*9)+(2*6)+(1*1)=139
139 % 10 = 9
So 134649-61-9 is a valid CAS Registry Number.
