158690-86-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 158690-86-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,8,6,9 and 0 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 158690-86:
(8*1)+(7*5)+(6*8)+(5*6)+(4*9)+(3*0)+(2*8)+(1*6)=179
179 % 10 = 9
So 158690-86-9 is a valid CAS Registry Number.
