159979-21-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 159979-21-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,9,9,7 and 9 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 159979-21:
(8*1)+(7*5)+(6*9)+(5*9)+(4*7)+(3*9)+(2*2)+(1*1)=202
202 % 10 = 2
So 159979-21-2 is a valid CAS Registry Number.
