135215-64-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 135215-64-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,2,1 and 5 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 135215-64:
(8*1)+(7*3)+(6*5)+(5*2)+(4*1)+(3*5)+(2*6)+(1*4)=104
104 % 10 = 4
So 135215-64-4 is a valid CAS Registry Number.
