155649-75-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 155649-75-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,5,6,4 and 9 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 155649-75:
(8*1)+(7*5)+(6*5)+(5*6)+(4*4)+(3*9)+(2*7)+(1*5)=165
165 % 10 = 5
So 155649-75-5 is a valid CAS Registry Number.
