215316-63-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 215316-63-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,5,3,1 and 6 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 215316-63:
(8*2)+(7*1)+(6*5)+(5*3)+(4*1)+(3*6)+(2*6)+(1*3)=105
105 % 10 = 5
So 215316-63-5 is a valid CAS Registry Number.
