21915-01-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 21915-01-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,9,1 and 5 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 21915-01:
(7*2)+(6*1)+(5*9)+(4*1)+(3*5)+(2*0)+(1*1)=85
85 % 10 = 5
So 21915-01-5 is a valid CAS Registry Number.
