847159-13-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 847159-13-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,7,1,5 and 9 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 847159-13:
(8*8)+(7*4)+(6*7)+(5*1)+(4*5)+(3*9)+(2*1)+(1*3)=191
191 % 10 = 1
So 847159-13-1 is a valid CAS Registry Number.
