62156-22-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 62156-22-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,2,1,5 and 6 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 62156-22:
(7*6)+(6*2)+(5*1)+(4*5)+(3*6)+(2*2)+(1*2)=103
103 % 10 = 3
So 62156-22-3 is a valid CAS Registry Number.
