7136-86-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 7136-86-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,1,3 and 6 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 7136-86:
(6*7)+(5*1)+(4*3)+(3*6)+(2*8)+(1*6)=99
99 % 10 = 9
So 7136-86-9 is a valid CAS Registry Number.
