307492-55-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 307492-55-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,7,4,9 and 2 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 307492-55:
(8*3)+(7*0)+(6*7)+(5*4)+(4*9)+(3*2)+(2*5)+(1*5)=143
143 % 10 = 3
So 307492-55-3 is a valid CAS Registry Number.
