1283716-33-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1283716-33-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,3,7,1 and 6 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1283716-33:
(9*1)+(8*2)+(7*8)+(6*3)+(5*7)+(4*1)+(3*6)+(2*3)+(1*3)=165
165 % 10 = 5
So 1283716-33-5 is a valid CAS Registry Number.
