215923-59-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 215923-59-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,5,9,2 and 3 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 215923-59:
(8*2)+(7*1)+(6*5)+(5*9)+(4*2)+(3*3)+(2*5)+(1*9)=134
134 % 10 = 4
So 215923-59-4 is a valid CAS Registry Number.
