78660-13-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 78660-13-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,6,6 and 0 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 78660-13:
(7*7)+(6*8)+(5*6)+(4*6)+(3*0)+(2*1)+(1*3)=156
156 % 10 = 6
So 78660-13-6 is a valid CAS Registry Number.
