135216-47-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 135216-47-6 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 6 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 135216-47:
(8*1)+(7*3)+(6*5)+(5*2)+(4*1)+(3*6)+(2*4)+(1*7)=106
106 % 10 = 6
So 135216-47-6 is a valid CAS Registry Number.
