71336-86-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 71336-86-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,3,3 and 6 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 71336-86:
(7*7)+(6*1)+(5*3)+(4*3)+(3*6)+(2*8)+(1*6)=122
122 % 10 = 2
So 71336-86-2 is a valid CAS Registry Number.
