155697-47-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 155697-47-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,5,6,9 and 7 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 155697-47:
(8*1)+(7*5)+(6*5)+(5*6)+(4*9)+(3*7)+(2*4)+(1*7)=175
175 % 10 = 5
So 155697-47-5 is a valid CAS Registry Number.
