155847-91-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 155847-91-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,5,8,4 and 7 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 155847-91:
(8*1)+(7*5)+(6*5)+(5*8)+(4*4)+(3*7)+(2*9)+(1*1)=169
169 % 10 = 9
So 155847-91-9 is a valid CAS Registry Number.
