215592-52-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 215592-52-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,5,5,9 and 2 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 215592-52:
(8*2)+(7*1)+(6*5)+(5*5)+(4*9)+(3*2)+(2*5)+(1*2)=132
132 % 10 = 2
So 215592-52-2 is a valid CAS Registry Number.
